Consider these four data sets. set a: {32, 12, 24, 46, 18, 22, 14} set b: {4, 12, 11, 14, 11, 5, 12, 13, 18, 14} set c: {5, 4, 9, 12, 14, 26, 22, 18} set d: {1, 1, 1, 2, 2, 3, 3, 4, 5, 6} the sets that show a positive skew are sets . the sets that show a negative skew are sets

SET A

The elements of this set are,



We arrange this data set in ascending order to get,



The median for this data set is



The mean for this data set can be calculated using the formula,



This implies that,




This data set is negatively skewed because the mean is less than the median.

SET B

This set contains the elements,



We arrange the elements of this set in ascending order to obtain,



The median for this data set is,



The mean is



.


This data set is negatively skewed because the mean I'd less than the median.

SET C

The set C has elements,


We arrange this set in ascending order to get,



The median of this data set is



The mean of this data set is




This is a positively skewed distribution because the mean is greater than the median

SET D

The elements of this set are



The median of this data set is



The mean is




This data set is positively skewed because the mean is greater than the median.
