Basically we have been provided with a stem and leaf plot, and we have to find three values from it, that are:

1) Median

2) Mode

3) Range

First write all the data in in ascending order.

96 , 98 , 104 , 106 , 106 , 106 , 110 , 113 , 113 , 115 , 124 , 129

1) Median

For even number of values median is the average between 2 middle values.

96 , 98 , 104 , 106 , 106 , 106 , 110 , 113 , 113 , 115 , 124 , 129

Median =( 106+110)/2

Median = 108

2) Mode

The number that appears most

Mode = 106

3) Range

Range = max number - min number

Range = 129 - 96

Range = 33
