min=129 ,1st quart=171, median=224, 3rd quart=344 ,maximum=438
Work Step by Step
The minimum is the smallest value in the data which is 129. List the numbers from least to greatest(129,165,171,173,221,227,333,344,347,438).The middle number is 221 and 227.Find the average between the two (221+227)/2=224. To find the first quartile you have to find the middle number between the minimum and the median which is 171 To find the third quartile you have to find the middle number between the median and the maximum which is 344 The maximum is the highest number in the data set which is 105.
