What percentage of the third graders scored less than 30 on the self-concept test?


To calculate the percentage of third graders who scored less than 30 on the self-concept test, we can use the histogram provided. The relevant information includes:

- The frequency of students scoring in the range of 20-30.
- The total number of students (N = 78).

From the histogram, it appears that approximately **2 students** scored between 20 and 30.

Now, to calculate the percentage:

\[
\text{Percentage} = \left( \frac{\text{Number of students scoring less than 30}}{\text{Total number of students}} \right) \times 100
\]

Let me calculate that.Approximately **2.56%** of the third graders scored less than 30 on the self-concept test.

Here are five related questions to consider:
1. What percentage of students scored more than 65?
2. How many students fall within the interquartile range (IQR)?
3. What is the range of scores for the middle 50% of the students?
4. What is the significance of the median score in this dataset?
5. How does the standard deviation help in understanding the distribution of scores?

**Tip:** The interquartile range (IQR) is a useful measure to understand the spread of the middle 50% of your data, giving insight into variability.
