Compare and contrast the central tendency of each group. Which group has the highest mean? Does it seem significantly higher? Which group has the lowest mean? Does it seem significantly lower? How do the medians compare to the means within each group – are they close or different to the means and why?
Which group has the greatest dispersion or spread? What does that tell you about that group? Which group has the lowest spread? What does that tell you about that group? Include standard deviation values and features you notice from the graphs.
Do all three of your sample groups seem like they could have come from the same population? Do any of the groups seem like they could have come from a different population? Explain.
