Importance of Statistical Parameters in Mathematics and Real Life

Statistics is one of the important branches of mathematics, and it deals with the collection, analysis, interpretation and presentation of data. A statistical parameter or more generally the population parameter is used to measure the probability distribution of a statistic, in other words it involves the random variable. This statistic is treated as a numerical property of a statistical population or a statistical representation. Assume that we have a recorded or tabulated class of distributions. When the index is also a parameter of the classes' members, then the group is parameterized.

Besides graphs, tables of numbers, statistics also involve using standard parameters to describe sets of numbers. There are two major divisions of these parameters. One part or group of parameters are used to measure how a set of numbers is centred around a particular point on a line scale in the data set. In other words, these are used where (around what value) the numbers bunch together. This category of parameters is called measures of central tendency, and they are mean median and mode. Another group of parameters measures deviation, an association of variables among the set of numbers.

Statistics are collections of mathematical equations used to investigate what is happening in the world around us. Today we live in the information era where we experience a numerous understanding regarding the world around us. We generally define the maximum of this information mathematically by employing statistics. When practised accurately, statistics tell us any past trends and predict what may happen in the future. For example weather forecasts, emergency preparedness, sports, player statistics, predicting disease, medical studies, genetics, consumer goods, quality analysis & testing and stock market etc.

Statistical parameters play an important role in determining the required output and drawing the conclusion for the given case or situation with the data set's help. Also, statistics assist in interpreting the characteristics and pattern of variability of a phenomenon in quantitative measurements. Statistics helps in extracting valid deductions, along with a measure of their reliability on the statistical population parameters from the sample data. In the normal distribution graph, some of the parameters can be shown along with their relationship. Also, standard deviation helps us in identifying how the data is spread around the central tendency, or central value, i.e. whether the distribution is small or big. Such parameters are usually instrumental in the analysis.

Parameters in statistics are an essential component of any statistical analysis. A parameter is defined as any numerical quantity that describes a given population, sample or some character in simple words. This means statistical analysis: the parameter tells us something regarding the entire population. Various statistical investigations need distinct kinds of parameters for the characterization of the given data. In many of the simple cases, the mean or median parameter is a unique indication of the data. For example, if a teacher wants to examine the students' performance in an examination, the median of the scores in the exam will be an excellent indication. In this way, statistical parameters can be used in many scenarios in our daily existence and mathematics.

Ways to inspire students to enjoy science

Education in science, technology, engineering, and mathematics (STEM education) is geared for a promising future. Operationalized skills requirements for employment have reduced, whereas those involving more specialized skills have risen. The government encourages learners to choose STEM sectors after school.

The school is still considered to be the primary learning location. Even so, social, intellectual and academic growth will extend beyond the classroom walls, giving them rights to explore and rise to higher levels. For example, by asking them interesting science questions, having quizzes in the classroom, and so on, we can inspire students to learn science subjects.

Few methods to inspire students to learn science

A complex beast is an inspiration. The latest and continuing analysis of student approaches to science education showed that many students believe science is important and useful, but do not want to study it independently. Here are the few strategies to inspire students to learn science subjects.

• Improving the image of science subject  

Most individuals consider science to be something complicated. In altering this viewpoint, teachers should play a significant role. They can teach kids how the environment has been transformed by science and say insightful things about the topic.

• Making it enjoyable 

At an early point, you should get learners passionate about science and focus on making it enjoyable and meaningful. To increase their interest in it, you should demonstrate hands-on activities.

• Be a powerful role-model 

If a child knows that the teacher can understand science and is enthusiastic about it, they may follow it. So behave as a role model.

• Connecting it to real life 

Students should be taught how science is being used in their daily lives. Because of science, we have cellular phones, computer games, laptops, and so on. It will be best if you tell children how your life is made easier by this stuff.

• To inspire them, take the initiative

If you scare kids by saying it's a complicated subject, you are guaranteed to fail, and they will be in trouble if they don't understand it. Under pressure, students usually respond negatively and then never learn the subject. To help them feel capable of learning the topic, start taking initiative steps.

• Modify the environment 

It is hard for someone to sit in a classroom all day, especially if you are energetic. 

So why not move the classroom to a different location to see how it affects the learning experience? Try taking kids to parks, nature walks, or even to the school playground. The healthy environment on their heads can also help them be very focused and alert.

• Highlight the importance of their careers 

Students know they are at school to be qualified in the field to get a promising career. To reap its benefits and attempt to link the topic with how it can be applied in a work environment.

• Be creative 

Rather than lecturing, teaching via discussion and games, encouraging students to ask, and show the topic with technical data like colourful maps, drawings and videos, etc. are more helpful. In the classroom performing the science-related quiz like chemistry questions, biology questions, physics questions, etc are very beneficial.

Conclusion

You must attempt to develop a genuine interest in the minds of students regarding science. By linking science to our lives, you could do so. Teachers should come up with exploratory and innovative opportunities to help them understand better science. Events, like a science fair, are held in several schools to inspire students. Having more activities like this would encourage students to perform fascinating research and stimulate a passion for science.

Animal Tissues and Types - Biological Facts

What are Tissues?

Cells are the basic structural and functional units of all living organisms. Tissues are groups of cells, which are similar in structure and perform a specific function. Each organ is made up of various tissues, and many organs together coordinate and constitute the organ system.

The complexity of the structural organisation of animals increases as we move from unicellular to multicellular organisms. In unicellular organisms, a single cell carries out all the physiological functions performed by a living organism such as digestion, respiration, reproduction, excretion, etc.

Let’s learn about the types of animal tissues and some interesting facts about them.

Facts About Animal Tissues and Types

Animal tissues are categorised into four main types, namely, Epithelial tissue, Connective tissue, Muscular tissue and Nervous tissue.

Epithelial Tissue

Epithelial tissue provides a covering to almost everything in our body and provides protection. It covers the body surface, organs and cavities. It acts as a barrier between different structures of the body. 

Simple epithelium is made up of a single layer of cells and is present as the lining of body cavities and ducts. The compound epithelium is made up of multiple layers of cells and acts as a protective covering, e.g. skin.

Epithelial tissue is further categorised into three types according to cell structure, they are:

• Squamous epithelium - form the diffusion boundary of blood vessels and alveoli in the lungs.

• Cuboidal epithelium - main functions are secretion and absorption, present in glandular ducts and tubules of kidneys.

• Columnar epithelium - line the stomach and intestine and perform secretion and absorption. The nucleus is present at the base of slender cells.

Ciliated epithelium cells bear cilia on their free surface and are part of respiratory and reproductive tracts.

The glandular epithelium is cuboidal or columnar cells specialised for secretion. Goblet cells are unicellular and salivary glands are multicellular.

Connective Tissue

Connective tissue provides support and transport substances. Examples of connective tissue are blood, bone, cartilage and adipose tissue.

Blood is a fluid connective tissue. It is made up of plasma, red blood cells, white blood cells and platelets. An interesting fact about our mature red blood cells is that they are devoid of a nucleus.

Cells of connective tissues with the exception of blood secrete fibres of collagen or elastin proteins, which are responsible for strength and flexibility.

Adipose tissue is a type of loose connective tissue. It stores fat.

Tendons and ligaments, which join bones to muscle and two bones together, respectively, are types of dense connective tissue.

Cells of cartilage tissue are known as chondrocytes and of the bones are known as osteocytes.

Muscle Tissue

Muscle tissue is made up of many long fibres arranged in a parallel fashion and are responsible for all the voluntary and involuntary movements in the body.

Muscle tissue is of three types:

• Skeletal muscle - They are associated with the skeletal system or bones. They are striated in appearance and responsible for locomotion and voluntary movements.

• Smooth muscle - They are nonstriated and present in the walls of blood vessels, reproductive and digestive tracts. They are under involuntary control of the nervous system.

• Cardiac muscle - Present in the heart. They are striated in appearance and are involuntary.

Nervous Tissue

Neural tissue is responsible for communication, control and regulation. It constitutes brain, spinal cord and peripheral nerves. Neurons are the basic unit of the nervous system. Glial cells are the support cells of nervous tissue.

The main parts of a neuron are:

• Dendrites - They are the short branched projections from the cell body. They conduct nerve impulses to the cell body.

• Cell body - It contains a nucleus, cytoplasm with cell organelles and Nissl’s granules.

• Axon - It is a long fibre, which transmits nerve impulses to a synaptic or neuromuscular junction, from the cell body. Each branch of an axon terminates in a synaptic knob, which contains neurotransmitters.

The Law Which Helps In Project Planning

Planning plays a vital role in the decision or task we take forward. Planning should be done carefully in order to achieve success. In case of failure, planning should also help in recovering back the loss. When we take up a project, a proper project management plan saves time and leads in a proper way. A well defined project plan will also have plan B outlined in case of failure of the project. This way of planning was said to be essential in Murphy's law.

Murphy’s law states that “Anything that can go wrong will go wrong”. This law was put forth by Edward J Murphy, who served as a major in the US Air Force, he had a specialization in development engineering. Let’s see how this law was coined.

History Of Murphy’s Law

When Edward J Murphy was working in the air-force, he observed that many tasks that were planned would fail at times. Since Murphy was into testing experimental designs, he noticed that things did not go exactly as planned. Many tasks required to have an alternate plan when the planned task deviated. Hence murphy came up with the law that states, “Anything that can go wrong will go wrong.” It tells us to be ready with the probability that something will go wrong and have an alternate.

Let’s know some of the probability cases where Murphy’s law is applied. Murphy's law has many applications in our day-to-day life.

• Assume you are buttering a piece of toast. Take two toasts, thinking about the probability that you might drop a toast. It’s better to have another option than regretting it. 

• When standing in a queue for billing with multiple checkouts, we should expect the other lines to move faster.

• When a mobile or laptop has some technical problem, when taken to a repair center, expect it to work normally without any repair.

After understanding Murphy's law, let us learn about Fermats Principle.

Principle of Least Time By Pierre de Fermat

Fermat's Principle is also known as the principle of least time. It helps us to know the path travelled by the light ray and the quickest time taken by the light. It deals with ray optics and wave optics. Fermat's principle was first stated by Pierre de Fermat, a French mathematician, in the year 1658. Fermat's principle is helpful for studying optical devices. This principle was the aid to explain the ordinary law of refraction of light.

According to the principle, light travelling between two points takes the path such that the optical length between the points is equal. 

Applications of Fermat's principle:

1. We know that light rays are rectilinear in a homogeneous medium. In any medium where the index of refraction is constant, light travels in a straight line.

2. The angle of reflection of a surface is equal to the angle of incidence. This is the Law of Reflection.

The Science of Energy

In Physics, the ubiquitous energy is defined as “the capacity for doing work.” The principle of conservation of energy states that the energy can neither be created nor destroyed, it can only be transformed from one form to another. To understand the validity of this statement let us consider an everyday example - A box slides down a hill, in this case, the potential energy that the box has acquired from being located high up on the slope is converted to kinetic energy. As the box slows down due to friction, the kinetic energy from the box’s motion is converted to thermal energy that heats the box and the slope. From this example, we understand that energy is not destroyed but merely transformed into another form of energy.

History of Energy

The term “energy” is derived from the Greek word “energeia”. The word literally translates to activity, operation. In 1807, Thomas Young coined the term “energy.” The theory of conservation of energy was formulated after major discoveries were made in the 19th and 20th centuries by Gustave-Gaspard Coriolis, William Rankine, and James Prescott Joule.

Types of Energy

Although there are different types of energy, they are broadly classified into potential energy and kinetic energy. Kinetic energy is the energy possessed by the body due to the virtue of its motion. Objects in motion are capable of causing a change and doing work. Potential energy is the energy stored in an object or system of objects. Potential energy has the ability to transform into a more obvious form of kinetic energy. In the next few sections, let us go over the various types of energy and understand their characteristics more clearly.

Types of Potential Energy

Chemical Potential Energy

The potential energy stored in the chemical bonds of substances is known as chemical potential energy. 

Elastic Potential Energy

Elastic potential energy is energy stored when a force is applied to deform an elastic object. The energy is stored until the force is removed and the object springs back to its original shape, doing work during the process.

Electric Potential Energy 

The potential energy needed to move a charge against an electric field is known as electric potential energy.

Gravitational Potential Energy

The potential energy stored in an object due to its vertical position or height is known as the gravitational potential energy.

Types of Kinetic Energy

Radiant Energy

Radiant energy is the energy created by electromagnetic waves and is commonly experienced by humans in the form of heat. 

Electrical Energy

The flow of electrons around a circuit results in electricity and is more commonly referred to as the electrical energy.

Mechanical Energy

Mechanical energy is the energy associated with the mechanical movement of objects.

Sound Energy

The human brain perceives the vibrations from the surroundings that reach the human ears as sound. The disturbance moves in the medium in the form of sound waves and reaches our eardrum. On reaching the eardrum, these waves are transformed into electrical signals and sent to the brain, which is later interpreted as sound. 

NEET Preparation With E-Learning

Competitive tests enable students to boost their skills in comprehending concepts deeply. It is required on a broader perspective when students participate and appear at such tests. It helps develop IQ, analytical and logical thinking, reasoning skills are enhanced, laying a strong foundation. 

Learning through online platforms has to be a groundbreaking initiative, especially for competitive-exam preparation. With the introduction of mobile applications, helpful platforms and other such revolutionary features, the educational field, and at the crux, students, are benefited immensely. One can envision learning at their own pace, at their own convenience. It is only making access to quality education easier. Educational applications, especially in the preparation of medical entrance tests - NEET UG, is a fast growing trend which is being embraced with wide arms.   

In every domain, competition in entrance tests is growing like never before. As a result, every aspirant must improvise to prepare themselves and be ready to face any type of hurdle.  

Why Should You Opt For Educational Apps For NEET Preparation? 

• Provision of updated study material online 

In this tech-savvy age, availability of e-books and other study material online is only favouring students to opt for educational apps for NEET preparation. It has emerged to be one of the most inexpensive and practical ways of getting one's hands onto them. Furthermore, students also are presented with regular updates on the date of exam, syllabus, pattern, registration process, counselling dates and more. 

• Option of video tutorials 

Educational apps provide students with the option of indulging in interactive video lessons to understand complicated and basic topics. Such engaging content facilitates effective and easy learning. This option can be availed on any device - laptop, tablets and even smartphones. Here, both teachers and students can upload and view videos only helping students to prepare for exams effectively. This serves as an important resource for students where instructions are directly obtained from mentors who demonstrate different shortcuts, brief on problem-solving techniques, time savers and other such tactics helpful to solve complex NEET questions in exams. This is another important reason why students opt for assistance on preparation rather than exploring self studying at this juncture.

• Availability 

Compared to the traditional means of academic assistance, hands down these platforms stand way ahead. The limit to the number of classes and time constraints at times may not sometimes yield very satisfactory results. But these online platforms promise to deliver and offer assistance round the clock. In most cases, 24*7 assistance can be expected. 

Additionally, one can book convenient slots and prepare for exams at their own convenience and pace. Mobile apps provide video lessons in both online and offline mode. Consequently, students can study without any interference.  

Some other perks offered are availability of test series, mock tests and many such options. It is a win-win situation to be a student in such times by all means.
