1. PROGRAMME B.COM SUBJECT QUANTITATIVE TECHNIQUE – I SEMESTER III UNIVERSITY VIJAYANAGAR SRI KRISHNADEVARAYA UNIVERSITY, BALLARI SESSION 08

2. RECAP Types of Classifications and Types of Series (Individual , Discrete & Continuous)

3. LEARNING OBJECTIVES The aim of the chapter is to make students to present data in textual and Tabular format including the technique of creating frequency distribution and working out bi-variate distribution table

4. LEARNING OUTCOMES After the Chapter , The Students Shall be able to Describe and Understand the Rules & Types of Classification, Frequency Distribution , Class Interval & its Types , Basic Principles Tabulation and The Sorting of Data.

5. SESSION - 9 Preparation of Frequency Distribution Table Meaning-- Discrete Series Problems -- 01

6. Meaning of Frequency Distribution: In Statistics, a frequency distribution table is a chart that summarizes values and their  frequency, i.e . the number of times the values have occurred. Steps of Frequency Distribution : Four steps they are we should form table of three columns, with heading of Observations, Tally marks and Frequency. In the first Column, place all possible values of variables or observations.

7. CONT., In the second column draw tally marks vertically against the observations. After a particular value has occurred four times, for the fifth occurrence we put a cross tally marks IIII ( 5 ) In the third column ( F requency column) count the number of marks corresponding to each value of the variable and place it. Discrete or Ungrouped Frequency distribution series In this case, the observations or variables are counted that how many times repeated is called the frequency of that class.

8. Example of Discrete Series Example: A survey was taken on Maple Avenue. In each of 20 homes, people were asked how many cars were registered to their households. The results were recorded as follows: 3,1,4 , 0, 2, 1, 5, 2, 1, 5, 4, 2, 3, 2, 0, 2, 1, 0, 3,2. Present this data in Frequency Distribution Table. Ans ; Number of Cars Tally marks Frequencies III 3 1 IIII 4 2 IIII I 6 3 III 3 4 II 2 5 II 2 Total 20

9. SUMMARY As we already discussed and learnt today on Classifications and Tabulation as below Preparation of Frequency Distribution Table Meaning-- Discrete Series Problems -- 01

10. MCQs 1. In an array, the data are: In ascending order In descending order ( c) Either (a) or (b) ( d) Neither (a) or (b) 2. The number of tally sheet count for each value or a group is called: Class limit ( b) Class width ( c) Class boundary ( d) Frequency

11. MCQs 3 . The frequency distribution according to individual variate values is called: (a) Discrete frequency distribution ( b) Cumulative frequency distribution ( c) Percentage frequency distribution ( d) Continuous frequency distribution 4. A series arranged according to each and every item is known as: Discrete series ( b) Continuous series ( c) Individual series ( d) Time series

12. MCQs 5 . A frequency distribution can be: Qualitative ( b) Discrete ( c) Continuous (d ) Both (b) and (c) ANSWERS 1. C 2. D 3. A 4. C 5. D
