One-way ANOVA - Winona State University
... Beside the graph you will now notice there are circles plotted. There is one circle for each group and each circle is centered at the mean for the corresponding group. The size of the circles are inversely proportional to the sample size, thus larger circles will drawn for groups with smaller sample ...

... After students do this exercise “by hand” (using a calculator), you may want to show them an applet that displays three different estimates regarding the Gettysburg Address. One is the mean word length. The other two are estimating population proportions; one is the proportion of “long” words define ...
