TOS4. from statistics (numerical facts) by statistics (statistics as a science or methodology). We can get a frequency polygon from a histogram, if the mid points of the upper bases of the rectangles are connected by straight lines. The total frequencies or value is equated to 360° and then the angles corresponding to component parts are calculated or the component parts are expressed as percentage of the total and then multiplied by 360/100 or 3.6, after determining these angles, the required sections in the circle are drawn. It carries a lot of communication power. In this article we will discuss about the Importance of Statistics in Education. Care should be taken to select the appropriate units of representation along the x-axis and the y-axis. Typically, they are re-sponsible for the pedagogical education of mathematics and statistics … Periodically, inspectors from the Ministry of Education as well as auditors do visit the schools to monitor how the … 5. We can have an overall comparison of two or more groups or frequency distributions by plotting the ogives concerning these distributions on the same co-ordinate axes. “Statistics may be called the science of counting.”, “Statistics is the science of estimates and probabilities.”, “Statistics is the science which deals with the collection, classification and tabulation of numerical facts as the basis for explanation, description and comparison of phenomena.”. We know that the data in the form of raw scores is known as ungrouped data and when it is organised into a frequency distribution, then it is referred to as grouped data. In education, statistics help with calculation and giving a summary of results for convenient and meaningful forms. Representation of data through the pie-diagram-Area of work expiated for by students of class XII: Numerical data of statistics may be represented by means of a picto-gram. It is what is used in the description for everyone to understand. Let us discuss them under separate heads. The data can be presented in a more attractive and an appealing form. Addition of cases on increase in the sample size irregularities. It will be the starting point of the curve. Statistics is both a formal science and a practical theory of scientific inquiry, and both aspects are considered in statistics education. 4. Therefore these bar diagrams are also referred to as bar graphs. 5. These irregularities in frequency distribution might have been minimized, if the data collected were numerous. The following points are to be kept in mind while constructing the histogram for a frequency distribution. The significant influence of statistics is in educational research. Hence, it follows that the method of enumeration by which a state,’ condition is known called statistics. 6. A slightly different procedure is to be adopted for calculating smooth frequencies for the class intervals at the extremes of the distributions. A good example is in the observation and administration of students. The scores in the form of actual class limits as 19.5-24.5; 24.5-29.5 and soon are taken as examples in the construction of histogram, rather than the written class limits as 20 – 24; 25 – 30 and so on. These diagrams or graphs are usually available in two forms, vertical and horizontal. 9 is the graphical representation of a cumulative percentage frequency distribution such as given in Table 2. 2. It is statistics which tells us why thus students who are similar in every other respect yet do not show similar achievement is one particular subject. is essentially a line graph for the graphical representation of the frequency distribution. It is essentially a closed curve while a frequency curve is not a closed curve. Statistics help tutors to accomplish their responsibilities, including monitoring the students and understanding the academic progress. 4. Where histogram is essentially the bar graph of the given frequency distribution, the frequency polygon is a line graph of this distribution. The mid-points of all the classes (or intervals) including two extra intervals are calculated. Basis of Scientific Approach to Problems: Statistics forms the basis of scientific approach to problems of Educational Psychology. The base of each rectangle is the width of the class-interval (1) and the height is the respective frequency of that class or interval. BASIC STATISTIICAL CONCEPTS DESCRIPTIVE STATISTICS • Describing the data gathered on a group and reaching to the conclusion about the same data, the statistics … In the construction of both these forms, the lengths of the bars are in proportion to the amount of variables or traits (height, intelligence, number of individual, cost and so on) possessed. The collection of statistics is important in educational management as highlighted above as it enables one as a school manager to perform duties with precision using calculated guesses. Statistics in Education • Measurement and evaluation are essential part of teaching learning process.
