The activity ends with a card sort where they must match the mean, median and standard deviation to a histogram and box plot. Histogram Maker. This can be useful if you want to compare the distribution of a continuous variable grouped by different categories. Visualizing a histogram is more intuitive, especially for a normal distribution curve, because it is easy to recognize that many data points exist within a center.
