Answer 1

Robert is using the following data samples to make a claim about the house values in his neighborhood:

House Value
A $250,000
B $275,000
C $300,000
D $267,000
E $250,000


Based on the data, should Robert use the mean or the median to make an inference about the house values in his neighborhood?

A. He should use the mean because it is in the center of the data.
B. He should use the median because it is in the center of the data.
C. He should use the median because there is an outlier that affects the mean.
D. He should use the mean because there are no outliers that affect the mean.

Answer 2

Typically, mean is preferred over median ***unless*** there are outliers, in which case median is preferred (median is outlier-resistant.)

so looking at your data, do you see any outliers?
