Answer:
The mean: 157 cm
The mode: 157 cm
The median: 157 cm
The range: 10 cm
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
