Visualize Measures of Center and Spread (Box Plot)
In this activity, you can change the mean and standard deviation for two different sets to see the impact on the box plots.
Experiment with different values for each sets' mean and standard deviation. Make sure to click on Randomize Numbers for the same means and standard deviations.
When can you be reasonably sure, for any given mean and standard deviation, that the two sets look reliably different from each other?
