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.

10. SUMMARY
As we already discussed and learnt today on
Classifications and Tabulation as below
• Preparation of Frequency Distribution Table -
Continuous Series(Exclusive) Problems-02

11. MCQs
1. The suitable formula for computing the number of
classes is:
(a) 3.322 logN
(b) 0.322 logN
(c) 1+3.322 logN
(d) 1- 3.322 logN
2. The number of classes in a frequency distribution is
obtained by dividing the range of variable by the:
(a) Total frequency
(b) Class interval
(c) Mid-point
(d) Relative frequency

12. MCQs
3 . If the number of workers in a factory is 256, the
number of classes will be:
(a) 8
(b) 9
(c) 10
(d) 12
4 . The largest and the smallest values of any given
class of a frequency distribution are called:
(a) Class Intervals
(b) Class marks
(c) Class boundaries
(d) Class limits

13. MCQs
5 . If there are no gaps between consecutive classes, the
limits are called:
(a) Class limits
(b) Class boundaries
(c) Class intervals
(d) Class marks
