A skewed distribution occurs when one tail is longer than the other.
Therefore, the Early May distribution is positive skew while the Late July distribution is negative skew.
Both distributions are skewed.
Then, the median of a skewed distribution is close to the highest point in the distribution.
Therefore, the median in Late July is of higher quality that the median in Early May.
Finally, notice that the probability of an apple being of more quality is higher in Late July than in Early May since there are more apples of better quality in the first period.
Apple quality is generally better in Late July than Early May.
