TABLE 3.27
Separate analysis table for Example 3.16
Column no. Size of items containing maximum frequency
10 11 12 13 14
1 12 14
2 12 13
3 13 14
4 11 12 13
5 12 13 14
6 10 11 12
Number of items 1 2 5 4 3
As 12 occurs the maximum number of times (5), the value 12 is the mode.
3.6.6.3 Computation of Mode for Continuous Frequency Distribution
In a continuous frequency distribution, rst the modal class is determined. This can be deter-
mined either by inspection or by grouping method. The required mode lies within the limits of
this modal class and is determined by the following formula:
M
0
= l +
ff
fff
i
10
102
2
−−
×
where M
0
is the mode, l the lower ...
