Question 70(iii)
Observe the data and answer the questions that follow:
16, 15, 16, 16, 8, 15, 17
What is the least number of data values that must be put in to change the mode to 17? Name them.

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
We will have to add at least three 17's to change the mode to 17. On adding three 17's, the frequency of 17 will be maximum, i.e. 4.
