This test was much too difficult for most people.
This test resulted in a huge range of scores. Everyone could do something but nobody could do it all.
This was the sort of test where you could either do everything or you couldn’t get started.
This test did not sort out the stronger students from the weaker ones. They all got similar scores.
In this test, the median and the mode scores were the same. There was a very big range of scores.
In this test, the median score was greater than the mode score.
In this test, the median score was smaller than the mode score.
Two groups of students took the test. One group had studied the work for two years. The other group had only just begun.

Place the graphs into the categories in which they belong. Most graphs will be used twice. (Assume that the mean is a better measure of center if the graph is not skewed.)

  • The best measure of center to describe this graph is the mean.
  • The best measure of center to describe this graph is the median.
  • This frequency graph shows symmetric data.
  • This frequency graph shows data skewed to the left.
