To identify the range and interquartile range.
Answer to Problem 19E
Range = 36
Interquartile range = 12
Explanation of Solution
Given information: 36 and 12
Formula Used:Range of the data=
Calculation:
Range and interquartile range (IQR) both measure the "spread" in a data set. Range is a quick way to get an idea of spread. It takes longer to find the IQR, but it sometimes gives us more useful information about spread.
The range is the distance from the highest value to the lowest value. The Inter-Quartile Range is quite literally just the range of the quartiles: the distance from the largest quartile to the smallest quartile, which is IQR=
So,
Range is greater than the Inter-Quartile Range.
Hence,
- Range = 36
- Interquartile range = 12
