Question

The median and mean of a unimodal statistical data are 42.4 and 40.6 respectively, then find its mode

Answer 1

by using the formula
---------------------------------
3 median = 2 mean + mode

3(42.5) = 2(40.6) + mode

127.5 = 81.2 + mode

mode = 127.5 - 81.2

= 46.3

hence mode = 46.3

Answer 2

By using the formula,

3 median = 2 mean + mode

3 (42.5) = 2(40.6) + mode

127.5 = 81.2 + mode

Mode = 127.5 -81.2

Mode = 46.3

Hence ,Mode =46.3
