Measures of Center - Dot Plot

Explore mean, median, and mode through the use of an interactive dot plot. Modify the line plot by dragging on Xs representing data. The measures of center are shown graphically and the values are computed dynamically as data is added to the graph. The maximum data can be adjusted to accommodate a wide array of values. One to ten data points can be displayed at a time.
