Question

Can someone check my answers?

Answer 1

mean and median is measures of the centre...

Answer 2

when data is skewed there are outliers. The problem with outliers they have a significant influence on the mean....
e.g. 1, 2, 3, 100 the mean is 26.25

eliminate the outlier 100 and the mean is 2

if you look at the 4 numbers the median is 2.5

which is the best measure of the centre mean or median... this idea needs to be applied to skewed data

Answer 3

is range of a data set affected by outliers...?

range is a measure of spread
