Data Set B: 20, 23, 28, 30, 44, 47
Select from the drop-down menus to correctly complete the statements.

Comparing the centers of the data sets, the median for Data Set A is ______
the median for Data Set B. The mean for Data Set A is ______ the mean for Data Set B.

Answer 1

The median for Data Set A is higher than the median for Data Set B.
The mean for Data Set A is the same as the mean for Data Set B.

The median is the middle number in each set.
For A, it is 31 and for B, it is 29.
To find the mean, you add up all the values and divide by 6. 
It is 32 for both sets.
