Meaning, Concept, Function, Role, Relevance & Importance of Statistics
Every discipline has some unique and special importance in any field of learning. The Importance of Statistics in Education is attributed to ‘how important Statistics is to every field of learning’ in relation to mathematics, education, business, science, etc. Most especially the importance and role of statistics in educational research.
Probably no subjects other than statistics demonstrate so clearly that there are several kinds of intelligence. Hence, statistics, if clearly understood, is a fascinating subject that has tremendous importance in computer, philosophy, mathematics, medical sciences, psychology, and education in general.
Statistics is used every now and then even outside the field of core Education such as Diagnosis and Programming. Statistics works hand-in-hand with Mathematics. Running away from Statistics is like running away from mathematics, you will be tired. This article will center mostly on the role and importance of Statistics in Education.
Though Statistical approaches sometimes appear to be insignificant to be noticed, but it doesn’t deny the degree of its value in everyday life.
Student-learning is measured more than ever before, and that means that the education field needs professionals who have expertise in educational statistics and measurement.
Definition of Statistics
Statistics is ‘the science concerned with developing and studying methods for collecting, analyzing, interpreting, and presenting empirical data.’
Statistics is a highly interdisciplinary field; research in statistics finds applicability in virtually all scientific fields and research questions in the various scientific fields motivate the development of new statistical methods and theory.
In developing methods and studying the theory that underlies the methods, statisticians draw on a variety of mathematical and computational tools.
Statistics deals with numerical facts that can be measured, enumerated, and estimated. The facts are homogeneous and related to each other. Facts must be accurate and it must be collected systematically.
Importance of Statistics in Education
Collection and Presentation of Data in a Calculated Systematic Manner
Statistics in education helps in the collection and presentation of Data in a well-arranged manner; Simply put, Statistics in educations helps in the orderly arrangement of data whether processed or not.
Data are a set of facts and they provide a partial picture of reality. Whether data are being collected with a certain purpose or collected data are being utilized, questions regarding what information the data are conveying, how the data can be used, and what must be done to include more useful information must constantly be kept in mind.
Since most data are available to researchers in a raw format, they must be summarized, organized, and analyzed to usefully derive information from them. This entails that unorganized or un-analyzed data are prone to unreliable and false output or results.
Furthermore, each data set needs to be presented in a certain way depending on what it is used for. Planning how the data will be presented is essential before appropriately processing raw data.
Statistics makes teaching and learning process more efficient
Statistics in Education make the Teaching and Learning Process more efficient in practice. Statistics in Education with special considerations to measurement and evaluation are essential parts of the teaching and learning process.
In this process, scores are being obtained and interpreted in order to make decisions. Statistics, therefore, enable us to study these scores objectively. It makes the teaching-learning process more efficient.
It helps in the Provision and Presentation of the Exact Type of Description
Statistics in Education helps in the provision of the exact type of description. Statistics helps the teacher to give an accurate description of the data. This could be found in the cases of administration of a pupil or observation of a child.
Statistics gives clear information about anything. Whenever Statistical approaches are employed, they automatically make the outcome or result to be simpler and easy to be understood even by a layman.
Every data in statistics is described with a property and values. The properties and values are assigned to a particular description that will enable a layman to grab immediately.
Take for example, the Google Search Console is a great tool that uses Statistics to show a user the happenings around his or her website. The statistics could show the user, how many traffics he is getting on his website every day. Again the Statistics will show the user his ranks for all the keywords in his website.
Google Search Console is a great type of tool that majorly uses statistics.
It conditions one to be definite and exact in procedures and thinking
Statistics show its importance in calculation and thoughts.
Sometimes due to lack of technical knowledge, the teacher becomes vague in describing the pupil’s performance. But statistics aid him or her to describe the performance by using proper language, and symbols. With the help of these statistical approaches, a definite and exact interpretation emerge.
Again, statistics help to guide one in thinking activities. When one thinks systematically through a calculated analysis and statistics, he or she thinks rightly and is likely to arrive at positive results quickly.
Think about Philosophy, the love of wisdom – the thinking bank. It maintains the use of statistics in thinking. Every good thinker utilizes every opportunity of Analysis.
Statistics helps in the Summary of Results
Statistics in education is important because it enables the calculation and adequate summary of the results in a meaningful and convenient form: statistics gives the order to the data.
It helps one to make the data precise, concise, and meaningful and to express it in a way that the persons involved will understand easily.
Statistics presents a clear and less ambiguous data. When the Statistical approach is introduced in the records or summary of results, it makes it easier and empirical to be observed.
Statistics aids one to Predict More Accurately
Guess what! 80% Predictions done every day comes from the statistics of related events or experience. When A game player plays bet for Real Madrid to win Aston Villa, it is taken for granted that he has studied the statistics of both teams and then conclude that Real Madrid will Aston Villa.
He must have studied the statistics of the players of both teams and then know which team will likely win, or which player will likely score a goal against the other one.
Statistics, therefore, helps one to predict more accurately and people may say, ‘Hey! This guy is a Genius’.
This could also be observed when a teacher predicts the future performance of the pupils: statistics enables the teacher to predict how much of a thing will happen under conditions we know and have measured.
For example, the teacher can predict the probable score of a student in the final examination from his entrance test score. But the prediction may be incorrect due to different factors. Statistical methods tell about how much margin of error to allow in making predictions.
Statistics helps in Analyzing some of the Causal Factors
Statistics enables the teacher to analyze some of the causal factors underlying complex and otherwise be-bewildering (confusing) events: it is a common factor that the behavioral outcome is a result of numerous causal factors.
The reason why a particular student performs poorly in a particular subject is varied and many. So with the appropriate statistical methods, we can keep these extraneous variables constant and can observe the cause of failure of the pupil in a particular subject
The importance of Statistics in Education includes Analysis of Causal Factors.
Quick Empirical Facts of Statistics
Generally, there are some quick empirical facts that will make you understand the importance of statistics in education quickly. These facts show how effective and valuable Statistics is in every field of learning.
1. Hospital Statistical Analysis
Statistical analysis is very necessary in the Hospital for the best test results. Imagine when Doctor Collins predicts disease based on statistical analysis, he is likely to present the best result out of it.
Suppose a patient has malaria according to the survey when statistical analysis is introduced, it will go a long way to present the accurate level of malaria in his or her body. Again, the already recorded statistics from history could give a hint on other diseases that are likely to arise.
A detailed statistical analysis will also dictate the effects the malaria will cause and possible causes of the disease.
2. The role Statistics in Prediction
Statistics aids in the prediction of future events. In a class of 89 students, their performance in continuous assessments and tests could determine who will take the First position or who will come out with the overall best result. It could even predict the most intelligent student among the 89 students in the class. This is what Statistics can do.
On the other hand, prior to a general election in a country, the statistical analysis of the political campaigns and awareness could make one to predict correctly who will win the election. Here Statistics plays a very vital role.
3. The Collection of Data and Information
The role of statistics in the collection of data and information is a very sensitive one. With a good statistical data, you can access varieties of information. With this, one can easily handle and manipulate the data accordingly.
For example, when the University management secures the data of the whole lecturers in the University, they could easily get information on what field they know best and then assign them to handle courses in that field.
Also, when the University management gets the whole data of the entire students in the university, they can determine the best courses to offer them, and even the best lecturers to assign the courses.
