The range is the difference between the largest and the smallest value:
RANGE =20-10=10
The first quartile is the median of the data values below the median (or at 25% of the data):
Q1=10+122=11
The third quartline is the median of the data values above the median (or at 75% of the data):
Q3=17+202=18.5
The interquartile range IQR is the difference of the third and first quartile:
IQR=Q3Q1=18.511=7.5
Results:
RANGE=10
IQR=7.5
