• Bi-Variate Frequency Distribution Table Meaning &
Problems-------- 01

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 - 14
• Bi-Variate Frequency Distribution Table Problems - 02

6. EXAMPLE 1
Prepare a bivariate frequency distribution table with
regard to marks scored by 20 students in two subjects
i.e., Marks in F.A and Q.T, With class interval 10
F.A 36 29 31 19 41 46 28 37 53 39
Q.T 57 43 41 31 61 63 19 53 75 61

10. SUMMARY
As we already discussed and learnt today on
Classifications and Tabulation as below
• Bi-Variate Frequency Distribution Table Problems - 02

11. MCQs
1 . A grouping of data into mutually exclusive classes
showing the number of observations in each class is;
(a) Frequency polygon
(b) Relative frequency
(c) Frequency distribution
(d) Cumulative frequency
2 . The class frequency divided by the total number of
observations is called:
(a) Percentage frequency
(b) Relative frequency
(c) Cumulative frequency
(d) Bivariate frequency

12. MCQs
3 . The following frequency distribution
Classes 10----20, 20----30, 30----40, 40----50, 50----60
Frequency 2 4 6 4 2
is classified as:
(a) Exclusive classification
(b) Inclusive classification
(c) Geographical classification
(d) Two-way classification

13. MCQs
4 . The following frequency distribution
Classes 0----4, 5----9, 10----14, 15----19, 20----24
Frequency 2 3 7 5 3
is classified as:
(a) Multiple classification
(b) Qualitative classification
(c) Inclusive classification
(d) Exclusive classification

14. MCQs
5 . The following frequency distribution
Classes; Less than 2, Less than 4, Less than 6, Less than 8
