Without the actual data from the datasets being discussed, it is impossible to definitively determine which statement is true. Each statement refers to specific characteristics of the datasets—median, spread (variability), interquartile range (IQR), and range. To evaluate the truthfulness of each statement, the data needs to be analyzed directly. Here’s what the statements mean in terms of statistical analysis:
1. **The median of the math scores is higher than the median of the science scores.**
- This statement compares the median (middle value) of the math scores to the median of the science scores.
2. **The math scores are less spread out than the science scores.**
- This refers to the variability or dispersion of the scores. A common measure of spread is the standard deviation, but it could also be interpreted through range or IQR.
3. **The interquartile range (IQR) of the science scores is lower than the IQR of the math scores.**
- The IQR measures the spread of the middle 50% of data points. A lower IQR means the middle half of the scores are closer together.
4. **The range of the science scores is higher than the range of the math scores.**
- The range is the difference between the highest and lowest scores. A higher range means a larger spread between the highest and lowest data points.
To determine which statement is true, you would need to calculate or have access to the following for each dataset:
- The median value of the scores.
- The overall spread or variability, typically through standard deviation or examination of the spread of data points.
- The IQR, calculated as the difference between the 75th percentile (Q3) and the 25th percentile (Q1).
- The range, calculated as the highest score minus the lowest score.
If you have these stats available, you can then directly compare them to assess the truth of each statement.
Which statement is true about the given datasets? (1 point) Responses The median of the math scores is higher than the median of the science scores. The median of the math scores is higher than the median of the science scores. The math scores are less spread out than the science scores. The math scores are less spread out than the science scores. The interquartile range (IQR) of the science scores is lower than the IQR of the math scores. The interquartile range (IQR) of the science scores is lower than the IQR of the math scores. The range of the science scores is higher than the range of the math scores.

so what do I pick
Since the actual datasets for math and science scores were not provided, the true statement among the given options cannot be determined conclusively without analyzing the datasets. However, I'll provide guidance on when each statement would be true based on common scenarios:
1. **The median of the math scores is higher than the median of the science scores.**
- You would pick this if, upon reviewing the datasets, the middle value (median) of math scores is greater than that of the science scores.
2. **The math scores are less spread out than the science scores.**
- This is true if the variability or dispersion (e.g., standard deviation, range) of the math scores is smaller compared to the science scores.
3. **The interquartile range (IQR) of the science scores is lower than the IQR of the math scores.**
- This would be the correct choice if the middle 50% of the science scores (IQR) spans a smaller range of values than the IQR of the math scores.
4. **The range of the science scores is higher than the range of the math scores.**
- This statement is true if the difference between the highest and lowest science scores is greater than the difference between the highest and lowest math scores.
If you have access to any summary statistics (medians, IQRs, ranges) for the datasets, compare them according to the above descriptions to select the true statement. If such data is unavailable, you may need to analyze the datasets directly or ask for the specific statistics to make an informed choice.
