Answer 2

Explanation:

Let's arrange the data set into an ordered increasing horizontal matrix.

A=[2, 4, 5, 5, 6, 7, 8, 9]

Mode of any data set is the most recurring number in the set. In the given set, ‘5’ occured maximum number of times.

So Mode is 5.

Median is defined as sum average of 2 middlemost terms(4th&5th term here) for an increasing patterned, even sized data set(8 elements here)

Median=(5+6)/2=5.5

So Median is 5.5

Mean= (sum of all the terms)/(number of terms) = (2+5+8+4+5+7+6+9)/8

Mean= 5.75
