Question

Plz help, keep getting wrong..True or false? The distrubution whose fiver number summary is shown below has at least one outlier... 4.2, 55.3, 73.4, 89.3, 132.2.... I got the upper range to be 187 and the lower range to be -17 so none of them would be outliers, but there was an outlier?

Answer 1

An outlier is a number that's radically different from the rest of the data. For example in the set 13, 25, 26, 29, 31, 33, 33, 94. Most of the data is in the upper twenties to lower thirties, so 13 would be an outlier, so would 94.

Hope this helps.
