Draw Conclusions

Two box plots have the same median and equally long whiskers. If one box plot has a longer box than the other box plot, what does this tell you about the difference between the data sets?

Communicate Mathematical Ideas

What you can learn about a data set from a box plot? How is this information different from a dot plot?

Analyze Relationships

In mathematics, central tendency is the tendency of data values to cluster around some central value. What does a measure of variability tell you about the central tendency of a set of data? Explain.
