From the great minds of Dash Young-Saver and Kevin McSorley, I’ve borrowed an activity to introduce sampling distributions for proportions. In the activity, students simulate random guesses, and their proportion correct is *supposed to * show up on the dot plot for all in the class to see.
However, something is going wrong, and I can’t figure out why.
Students take 24 guesses on slide 4, and they are instructed to enter the proportion of correct answers as an exact fraction. On slide 5, each student’s sample/simulation proportion should show as a dot in the shared dotplot.
When I look at mine in editing mode, the plot range looks good:
However, when I had a small group of students work on it, their points plotted well outside of this range:
