Question

Observe the data and answer the questions that follow:

16, 15, 16, 16, 8, 15, 17

At least how many and which value(s) must be put in to change the mode to 15?

Answer 1

Given data; 16, 15, 16, 16, 8, 15, 17

Arranging the given data in ascending order, we have 8, 15, 15, 16, 16, 16, 17

Atleast two 15’s should be added to change the mode to 15. On adding two 15’s the frequency of 15 will be maximum, i.e. 4.
