A biologist measures the heights, in centimeters, of five seedlings in a laboratory. The heights are $12$ , $15$ , $8$ , $21$ , and $14$ . What is the range, in centimeters, of these heights?

Cevap: 13 centimeters

Cevap

To find the range of a dataset, subtract the minimum value from the maximum value. In the given dataset of seedling heights (

12

15

8

21

, and

14

), the maximum height is

21

centimeters and the minimum height is

8

centimeters. Calculating the difference gives

21 - 8 = 13

centimeters.

Adım Adım Çözüm

Identify the maximum and minimum values in the dataset.

The maximum value is

21

and the minimum value is

8

The range is defined as the difference between the largest (maximum) and smallest (minimum) values in a data distribution.

Subtract the minimum value from the maximum value to calculate the range.

21 - 8 = 13

Subtracting the minimum value of

8

from the maximum value of

21

yields the range of the dataset.

Anahtar Kavram

The range of a dataset measures the spread of the data and is calculated by subtracting the minimum value from the maximum value.
