Question 1020614
Hi there,
Arrange numbers in order:
55 60 72 75 78 81 83 84 85 86 90 91 92 93 94 95 97 98 100 100
Median = 88 (between 86 and 90)
Mode = 100 (appears more than once)
Range = 100 - 55 = 45
Mean = total/ number of scores
Mean = 1709/20
Mean = 85.45 (2 decimal places)
Hope this helps :-)
