The mean: 157 cm

The mode: 157 cm

The median: 157 cm

The range: 10 cm

Step-by-step explanation:

To calculate the mean add all the heights and divide them by the number of heights.

(159 + 155 + 153 + 154 + 157 + 162 + 152 + 160 + 161 + 157) ÷ 10 =  157 cm

The mode is 157 cm because that is the most frequent number.

The median height is the middle number, so first place them in order.

152, 153, 154, 155, 157, 157, 159, 160, 161, 162

The median height is 157 cm

The range is the difference between the highest and lowest number.

162 - 152 = 10
