A reporter is writing an article on home rental prices. The reporter is deciding whether to report a finding on home rental prices using the mean or the median. The following statistics were found.

 

Mean $1850                Standard Deviation $210

Minimum $1235         Median $1600             Maximum $2890         Interquartile Range $180

 

Which measure of central tendency, mean or median, should the reporter use?

• The mean because the mean rent price is higher than the median rent price, showing the mean is more accurate central tendency than the median.

• The mean because the minimum rent price is farther away from the mean than the median, showing the mean is more accurate central tendency than the median.

• The median because the interquartile range is smaller than the standard deviation, showing the median is more accurate central tendency than the mean.

• The median because the maximum rent price is an outlier that skews the mean rental price higher, showing the median is more accurate central tendency than the mean
