Question

find the range for the group of data items. 20, 21, 22, 23, 24 the range is (simplify your answer.)

Explanation:

Step1: Recall the formula for range

The range of a set of data is calculated as the difference between the maximum value and the minimum value in the set. The formula is \( \text{Range} = \text{Maximum value} - \text{Minimum value} \).

Step2: Identify the maximum and minimum values

In the given data set \( 20, 21, 22, 23, 24 \), the minimum value is \( 20 \) and the maximum value is \( 24 \).

Step3: Calculate the range

Using the formula for range, we subtract the minimum value from the maximum value: \( 24 - 20 = 4 \).

Answer:

\( 4 \)
