Given:
Data Set: 60 items
Median: 25
lower quartile or Q1: 21
upper quartile or Q3: 42

IQR = Q3 - Q1 = 42 - 21 = 21

The DISTRIBUTION IS SKEWED TO THE RIGHT.

distance between median and Q1: 25 - 21 = 4
distance between Q3 and median: 42 - 25 = 17

Since the distance between Q3 and median is greater than the distance between the median and Q1, the distribution is skewed to the right.

Answer:

It should have been There are no outliers in this distribution
