<span>First, you would normally need to order the numbers from least to greatest, but since the numbers are already in order we can skip this step.
</span><span>24,24,28,32,40,42
</span><span>The
median is the data value in the middle of the data set or, in this case
because there is an even number of values, the average of the two
middle values.
Median: 30
The first quartile value is the median for the numbers before the median. So find the median of</span><span> 24, 24, 28, which is just the middle number.
First quartile: 24
Finding the third quartile is exactly the same as the first, except use the values after the median. (</span><span>32, 40, 42)
Third quartile: 40
The IQR (Inter-quartile Range) is just the the third quartile minus the first quartile.
40 - 24 = 16 </span> <span>So here are your answers
