Question

what was the range of name lengths?

Explanation:

Step1: Recall the formula for range

The range is calculated as \( \text{Range}=\text{Maximum value}-\text{Minimum value} \).

Step2: Identify maximum and minimum values

From the bar - chart (assuming the x - axis represents frequency and y - axis represents the number of letters in names), the minimum number of letters (minimum value) is \( 2 \) and the maximum number of letters (maximum value) is \( 10 \).

Step3: Calculate the range

Substitute the values into the formula: \( \text{Range}=10 - 2\).

Answer:

\(8\)
