If you have a distribution of 50 scores, and you want 5 intervals, what should be the size of your class interval?
Group of answer choices

5

10

50

25

To determine the size of the class interval, you use the formula:

\[
\text{Class Interval Size} = \frac{\text{Range of Data}}{\text{Number of Intervals}}
\]

In your case:
- You have 50 scores, which means the **range** is assumed to be 50.
- You want 5 intervals.

So, the class interval size would be:

\[
\frac{50}{5} = 10
\]

Thus, the correct answer is **10**.

Here are 5 related questions to deepen your understanding:
1. How would you calculate the range if the data set values were given?
2. What happens to the class interval if you increase the number of intervals?
3. How can you decide the optimal number of intervals for a given data set?
4. Why is it important to have equally sized class intervals in statistics?
5. How would the result change if the range of data were not equal to the number of scores?

**Tip:** When creating a histogram, ensure the number of intervals is appropriate to avoid too much or too little detail in the data distribution.
