Probing questions
Two distributions both have the same range but the first one has a median of 6 and the second has a mode of 6. Explain how these two distributions may differ.
Find five numbers that have a mean of 6 and a range of 8.
How did you do it?
What if the mean was 6 and the range 8?
What if the mode was 6 and the range 8?
