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.
K= 10(-7) -19
k= -70-19
k=-89
You would want to divide 216 by 18 and by doing that you would get 12.
