Question

what is the interquartile range of this set of data 5, 5, 6, 7, 9, 11, 14, 17, 21, 23

Answer 1

Answer:

11.00

Step-by-step explanation:

To calculate the interquartile range of the data:

5, 5, 6, 7, 9, 11, 14, 17, 21, 23

To calculate the interquartile range we need to lower quartile $(X_L)$ and upper quartile $(U_L)$.

The lower interquartile $(X_L)$ of the data set is: 6.

The upperquartile $(U_L)$ of the data set is: 17.

Therefore, the interquartile range is:  $(X_U-X_L)=(17-6)=11$.

Answer 2
