The distribution of backpack sizes is best described as __________. So, the __________ is a more appropriate measure of variation than the __________.
Answer options:
1. uniform, mean, median
2. symmetric, mean, mode
3. skewed, median, mean
4. normal, median, range
The correct answer is: 3. skewed, median, mean.
Explanation: If the distribution of backpack sizes is skewed, it suggests that the sizes are not evenly distributed and may have a longer tail on one side. In such cases, the median is a better measure of central tendency because it is less affected by extreme values compared to the mean. Therefore, while the median provides a more accurate reflection of the typical size, the mean could be misleading due to skewness.
