Find the mean, median, mode, and range of each data set below. If there is no mode, write “no mode”; if there is more than one mode, write all the numbers that happen most often.

Question

33, 33, 38, 39, 38, 34, 33, 30, 33, 32, 31, 34, 38, 40, 42

Answer 1

for mean: add them up, then divide by the number of data values
for median: put them in order from smallest to largest, the number in the middle is the median
mode: the data value which appears most often. (I see a lot of 33s)

Answer 2

range = largest minus smallest
