LESSON TOPIC / TITLE   :  CHAPTER 14:  STATISTICS	ESTIMATED DURATION:  This lesson is divided into ten modules and it is completed in ten class meetings.

PRE- REQUISITE KNOWLEDGE:-

Knowledge of statistics (Bar graph, Mean, mode and median) Class 8

TEACHING AIDS:- 

Green Board, Chalk, Duster, Charts, smart board, projector and laptop etc.

METHODOLOGY:- 

Demonstration and Lecture method

OBJECTIVES:-

• Introduction of statistics.
• Explanation of Bar graph.
• Histogram with varying base lengths
• Frequency Polygon.
• Concept of Mean, Mode and Median.

PROCEDURE :-

Teacher will ask the class about the different types data they come across. Teacher will also ask some questions related to the presentation of these data. When the class starts giving some responses then teacher will introduce the topic statistics step by step as follows.

S. No	TOPIC  [For Complete explanation Click Here]
1	Introduction: The word ‘statistics’ appears to have been derived from the Latin word ‘status’ meaning ‘a (political) state’. In its origin, statistics was simply the collection of data on different aspects of the life of people. Now Statistics deals with collection, organization, analysis and interpretation of data. In the first sentence, statistics is used in a plural sense, meaning numerical data. In the second sentence, the word ‘statistics’ is used as a singular noun, meaning the subject which deals with the collection, presentation, analysis of data as well as drawing of meaningful conclusions from the data.
2	Activity Divide the students of the class into four groups. Allot each group the work of collecting one of the following kinds of data: (i) Heights of 20 students of their class. (ii) Number of absentees in each day in the class for a month. (iii) Number of members in the families of their classmates. (iv) Heights of 15 plants in or around the school.
3	When students will collect data then teacher will conclude the following points. Primary Data:- In the first case, when the information was collected by the investigator herself or himself with a definite objective in her or his mind, the data obtained is called primary data. Secondary data:- In the second case, when the information was gathered from a source which already had the information stored, the data obtained is called secondary data.
4	Presentation of Data: Here teacher will explain the different methods of representing the grouped and ungrouped data. The methods are as follows: Representing the data by using Frequency Distribution table for ungrouped and grouped data by using tally marks and frequency. Teacher will explain the topic by taking some examples. C-I Tally Marks Frequency                   Total
5	Geometrical Representation of Data There are three methods of representing the data geometrically a) Bar Graph b) Histogram c) Frequency Polygon d) Frequency Ogive (To be studied in class 10)
6	Bar Graph. Here teacher will explain the method of making Bar Graph (on the graph paper) for the ungrouped data by taking some examples.
7	Histogram of uniform width and varying width Here teacher will explain the complete method of making histogram for the grouped data by taking some demo questions. Teacher may provide some problems to the students for practice.
8	Frequency Polygon. Teacher will explain the method of making the frequency polygon by taking some demo questions. Teacher may also provide some problems to the students to assess their performance and learning skills.
9	Different measures of Central Tendency Now teacher will introduce the different modes of central tendency. There are three measures of central tendency Mean, Mode, Median Mode of the ungrouped data Most frequent observation is called mode
10	Mean of ungrouped frequency Mean is the method of finding the average of the given data. Mean of ungrouped data without frequencies                  =   =    Here:   xi are the different observations.               n is the total number of observations. Mean of ungrouped data with frequencies Mean   =      Here fi  is the frequencies
11	Median of ungrouped data Median can be calculated by using the following steps 1) Write the given observations in ascending order. 2) Count the number of observations(n). 3) If n  is odd then Median =    observation 4) If n is even then Median =    REFERENCES:- NCERT text book NCERT EXEMPLER https://www.cbsemathematics.com

EXPECTED OUTCOMES:-

After studying this lesson students will be able to understand,

• Different types of data.
• Frequency distribution table.
• Different geometrical methods of representing the data (Bar Graph, Histogram, Frequency Polygon)
• Different methods of central tendency (Mean, Mode, Median)

STUDENTS DELIVERABLES:-

Review questions assigned by the teacher.
Solve N.C.E.R.T problems with examples.
Students can also prepare a Power Point Presentation showing different methods of finding central tendency.
Students can solve the assignment on statistics given by the teacher

EXTENDED LEARNING:-

Students can extend their learning by studying basic concepts and formulas of mathematics through the Resource Centre Mathematics and can find interesting topics on mathematics at the site https://www.cbsemathematics.com/

ASSESSMENT TECHNIQUES :-

Assignment sheet will be given as home work at the end of the topic. Separate sheets which will include questions of logical thinking and Higher order thinking skills will be given to the above average students.
Class Test, Oral Test, worksheet and Assignments can be made the part of assessment. Re-test(s) will be conducted on the basis of the performance of the students in the test.
