Question
If you have a distribution of 50 scores and you want 5 intervals, what should be the size of the class interval?
Choose one:
- 50
- 25
- 10
- 5
Solution
To find the size of the class interval, you need to divide the total number of scores by the number of intervals you want.
Here's how you do it:
Step 1: Identify the total number of scores. In this case, it's 50.
Step 2: Identify the number of intervals you want. In this case, it's 5.
Step 3: Divide the total number of scores by the number of intervals.
So, 50 (total scores) ÷ 5 (intervals) = 10.
Therefore, the size of the class interval should be 10.
