1. When might someone prefer mode over mean or median to describe a data set’s central tendency? When is the median preferred over the mean to describe a variable?
2. Mean or average is a one way to describe scores in a distribution, but this does not tell us everything we need to know. What else might be important to know in addition to the measure of central tendency?
3. Why might someone want to use a bar, line, box plot, or pie chart to display data? How does the data displayed differ for these different types of charts?
