Answer 1

We can see that the modal class is 140 - 159 with maximum frequency 60.

Estimated Mode = L + fm - fm-1 (fm - fm-1) + (fm - fm+1) X W where: . L is the lower class boundary of the modal group fm-1 is the frequency of the group before the modal group fm is the frequency of the modal group fm+1 is the frequency of the group after the modal group • w is the group width .

L = 140

f_m-1 = 40

f_m = 60

f_m+1 = 30

w = 20

$Mode = 140 + \frac{60 - 40}{(60-40) + (60-30)} * 20$

$Mode = 140 + \frac{2}{5} * 20$
