Question

The table below shows the number of hours some business people in two states spend in meetings each week:


State A 21 23 24 22 24 25 23 23 22
State B 24 22 20 23 23 50 20 46 21


Part A: Create a five-number summary and calculate the interquartile range for the two sets of data. (6 points

Answer 3

A five-number summary of any set of any set of data usually consists of the following:
Minimum Value
Lower Quartile Value
Median Value ("Middle" Value)
Upper Quartile Value
Maximum Value

Thus, Interquartile Range (IQR) = Upper Quartile - Lower Quartile.

This is essentially the 'spread' or the 'range' of the middle 50% of the ordered data set.

To obtain these figures for each of the two data sets given in the question, we need to first arrange the data from smallest to largest in each case. The maximum and minimum values should be easy enough to find then, as they are simply the values at the ends of our ordered sets. Do you know anything about how to calculate or work out the median and the upper/lower quartiles @ndavis ?

Are you there @ndavis .... if you don't really know I will try and explain it to you!
