35, 42, 37, 41, 39, 44, 37, 39, 41, 40, 45, 38, 34, 37
The -number summary will be calculated as follows:
Re-arranging the set in ascending order we shall have:
34, 35, 37, 37, 37, 38, 39, 39, 40, 41, 41, 42, 44, 45,
From the set above:
Minimum =34
1st quarter = 37
Median= 39
3rd Quarter =41
Maximum =45
Mean=39.21
thus since mean is almost equal to median, both median and mean could be used to represent the distribution.
