Answer 5

its defined as the difference between the 25th percentile to the 75th percentile of the data. So line up the numbers from lowest to highest and find out the 25th and 75h percentile. So you have 8 terms so the median will be 192, the lower quartile is 125 and the upper quartile is 242.5. So then the range is 242.5-125=117.5.
