Try another version of this question Find the mean `\overline x`, median, standard deviation `s`, and variance `s^2` for the G-rating data set with and without the outlier and then record them in the table below. For the ease of comparison, you will re-enter the measurements with the outlier. You may need to refer to the equation for calculating variance.
Rating Mean Median Standard Deviation Variance `\overline x` `s` `s^2` G rating with the outlier G rating without the outlier Rating Mean Median Standard Deviation Variance `\overline x` `s` `s^2` G rating with the outlier 92.1 90 25 625 G rating without the outlier 90.3 89.5 11.8 139.24
