2. CONTENT CONCEPT OF STATISTICS APPLICATION OF STATISTICS IN EDUCATION APPLICATION OF STATISTICS IN RESEARCH

3. Definition : The science of statistics is essentially a branch of applied mathematics and can be regarded as a mathematics applied to observation data –(R.A Fisher) Concept : statistics is the branch of applied mathematics which deal with the study of collection ,organization ,analysis , interpretation and presentation of quantitative data CONCEPT OF STATISTICS :

4. Measurement and evaluation are essential elements of teaching learning process In this process we obtained the scores and interpret these scores in order to conclude the performance of students Statistics makes teacher capable to study these scores objectively Hence, statistics makes teaching learning process more efficient and effective A PPLICATION OF STATISTICS IN EDUCATION :

5. It helps teacher to provide the most exact type of description : when we want to know about the pupil we administer a test or observe the child then from the result we describe about the pupil’s performance or trait .statistics helps the teacher to give an accurate description of the data EXAMPLE : A math’s teacher conduct a test of 10 marks following are the obtained marks by the students 2,3,4,4,4,5,5,8,8,9 Description of data are 9 =best performance (as it is highest score obtained) 2 =worst performance (lowest obtained score) 5.2=average performance of the class (mean) Role of statistics in education

6. It makes the teacher definite and exact in procedures and thinking : sometimes due to lack of technical knowledge the teachers become vague in describing the student’s performance in certain situation field of statistics enables him to describe performance by using proper language and symbols which makes the interpretation definite and exact.

7. Above pie chart interpret attendance record of students among different subjects according to this highest attendance has been recorded in economics and lowest attendance is in physics hence it may depend upon interest of students in subject

8. It enables the teacher to summarize the results in a meaningful and convenient form : Statistics gives order to the data. It helps the teacher to make the data precise and meaningful and to express it in an understandable and interpretable manner EXAMPLE : O,1,1,2,2,2,3,4,5,6 SUMMARY : MEAN = 2.6 MEDIAN = 2 MODE = 2 RANGE = 6

9. It enables teacher to draw general conclusions : statistics helps teacher to draw general conclusion as well as extracting conclusions .statistics steps also help to say about how much faith should be placed in any conclusion and about how far we may extend our generalization It helps the teacher to predict 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 EXAMPLES: The teacher can predict the probable score of a student in the final examination from his entrance test score .but the prediction may be erroneous due to different factors. statistical methods tell about how much margin of error to allow in making predictions

10. Statistics enables the teacher to analyse some of the causal factors underlying complex and otherwise Be- wildering events : it is a common factor that the behavioural outcome is a resultant of numerous causal factors . the reason behind the poor performance of the students in a particular subject are varied and many . So with the appropriate statistical methods we can keep this extraneous variables constant and can observe the cause of failure of the pupil in a particular subject EXAMPLE : Students of class ninth obtained overall very lowest result in chemistry subject by the help of statistics teacher become capable to find out the reason behind this poor performance that is lack of understanding as well as chemistry teacher become failure to build interest in chemistry subject

11. APPLICATION OF STATISTICS IN RESEARCH Statistics play a vital role in research . For example statistics can used as in data collection ,analysis ,interpretation , explanation and presentation .Use of statistics will guide researchers in research for proper characterization , summarization presentation and interpretation of the result of research. It is important for researchers and also consumers of research to understand statistics so that they can be informed , evaluate the credibility and usefulness of information , and make appropriate decisions.
