Question

True or False?
The distribution whose five-number summary is shown below has at least one outlier:
21.7, 55.3, 73.4, 89.3, 140.1

Answer 1

False, you have to find the IQR which is 89.3-55.3= 34.
If a number falls more then 1.5IQR below the first quartile or above the third quartile, then there is an outlier. Neither of these cases is true. Thus, there are no outliers.

Answer 2

is it always 1.5*IQR??

Answer 3

yeah
