Answer:
IQR = 14
Step-by-step explanation:
The interquartile range is the difference between the upper quartile and the lower quartile.
First find the median.
The median is the middle value of the data arranged in ascending order.
If there is no exact middle then it is the mean of the values either side of the middle.
There are 10 values in the data set, thus the middle is between 43 and 46.
median =
= 44.5
The upper quartile is the middle value of the data to the right of the median
= 49
The lower quartile is the middle value of the data to the left of the median
= 35
Hence IQR = 49 - 35 = 14
