Question

question
the graph below represents the result of a survey in which a number of students reported how many letters were in their last names.
name length
bar graph with x - axis number of letters (0 - 10) and y - axis frequency (number of students)
what was the range of name lengths?
answer attempt 1 out of 3
letters

Explanation:

Step1: Identify max and min values

From the graph, the number of letters (name length) ranges from 2 (minimum, since the first non - zero bar is at 2) to 10 (maximum, the last bar is at 10).

Step2: Calculate the range

The formula for range is \( \text{Range}=\text{Maximum value}-\text{Minimum value} \). Substituting the values, we get \( 10 - 2=8 \).

Answer:

8
