Since the distribution is symmetric, the mean and the median of the distribution are equal.
What are the mean and the median of a distribution?
- The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.
- The median of a distribution is the value that separates the bottom 50% of the distribution from the upper 50%, that is, the middle value of the distribution.
When a distribution is symmetric, the mean and the median are equal. From the dot plot in this problem, the distribution is uniform(as all outcomes are equally as likely, that is, they have the same frequency in the dot plot), and symmetric, hence the the mean and the median of the distribution are equal.
