Question

Mean:
August – 13614.5
September - 23417

Median:
August - 13215
September - 21685
What do the values of mean and median tell you about the shape of the distribution of data.

Answer 1

The difference between the mean and median can provide insight into the skewness of the distribution. When the mean is greater than the median, it typically indicates that the distribution is right-skewed, meaning there are a few very high values that are pulling the average up. Conversely, when the mean is less than the median, the distribution is left-skewed, indicating that there are a few very low values pulling the average down. In this case, the mean is higher than the median for both August and September, suggesting that the distributions are both right-skewed.
