Students estimate the mean and median of a distribution represented by a dot plot or a histogram.
Students indicate that the mean is a reasonable description of a typical value for a distribution that is symmetrical but that the median is a better description of a typical value for a distribution that is skewed.
Students interpret the mean as a balance point of a distribution.
Students indicate that for a distribution in which neither the mean nor the median is a good description of a typical value, the mean still provides a description of the center of a distribution in terms of the balance point.
