Use the image to answer the question.
Two box plots. One is labeled 'Math Scores' while the other is labeled 'Science Scores.' The plots are placed over a number line that ranges from 0 to 30 in increments of 5. The 5 number labels typical to box plots are available for both. The box plot for math scores shows the following labels: minimum: 5; first quartile: 10; median: 15; third quartile: 20; maximum: 25. The box plot for science scores shows the following labels: minimum: 6; first quartile: 12; median: 16; third quartile: 20; maximum: 24.

To analyze the box plots' data, we can calculate the necessary statistics.
1. **Interquartile Range (IQR)**:
- IQR is calculated as the difference between the third quartile (Q3) and the first quartile (Q1).
- For Math Scores:
- Q1 = 10, Q3 = 20
- IQR (Math) = Q3 - Q1 = 20 - 10 = 10
- For Science Scores:
- Q1 = 12, Q3 = 20
- IQR (Science) = Q3 - Q1 = 20 - 12 = 8
Comparison: IQR of Science (8) is lower than IQR of Math (10).
2. **Median**:
- For Math Scores, the median is 15.
- For Science Scores, the median is 16.
Comparison: The median of Math (15) is lower than the median of Science (16).
3. **Spread**:
- Spread can be measured using the range or IQR.
- Range is calculated as the maximum minus the minimum.
- For Math Scores:
- Range = Maximum - Minimum = 25 - 5 = 20
- For Science Scores:
- Range = Maximum - Minimum = 24 - 6 = 18
Comparison: The range of Science (18) is lower than the range of Math (20), meaning math scores are more spread out.
4. **Statement Evaluation**:
- The interquartile range (IQR) of the science scores is lower than the IQR of the math scores. **(True)**
- The median of the math scores is higher than the median of the science scores. **(False)**
- The math scores are less spread out than the science scores. **(False)**
- The range of the science scores is higher than the range of the math scores. **(False)**
Based on the analysis, the statement that is true is:
