To determine which data set is best described by the median, we need to consider the characteristics of the distributions in each graph.
-
Data Set A: The values appear to cluster around the 7-9 range, and there are a few zeros at the higher end (10-12). The distribution looks somewhat balanced and not heavily skewed, suggesting the mean could be a valid measure of center as well.
-
Data Set B: The distribution has a varied spread with some values concentrated around 5-9, but there is a small number of occurrences for each value, making the distribution more uniform across the data range.
-
Data Set C: This distribution is heavily skewed to the right (with 1, 3, and 6 at the highest values), indicating that the mean could be influenced by the outliers at the higher end of the data. In this case, the median would be a better representation of the central tendency because it is less affected by the extreme values.
Given the characteristics of each data set, the most appropriate answer would be:
data set C because the distribution is skewed.
This is because the median is robust to skewness and is a better measure of center for skewed distributions.
