What is the median of this set of data: 593, 588, 540, 434, 420, 398, 390, 375

C. 427

The median is the middle number of all the data

Since there is an even number of data points the median is in between the middle two data points (434 and 420)

To find this: 434-420=14
14/2=7
434-7=427
420+7=427
