The number of dots tells us how many times we need to add the actual number underneath the dots. So you need to use both.

Which number should you use for the mean?

Let's suppose we have the next set:

{2, 2, 2, 4, 5, 5, 6}

If you graphed it in a dot plot, then you will have:

  • 3 dots above the number 2.
  • 1 dot above the number 4.
  • 2 dots above the number 5.
  • 1 dot above the number 6.

A total of 7 dots.

To find the mean, we just compute:

[tex]M = \frac{2 + 2 + 2 + 4 + 5 + 5 + 6}{7} = 3.7[/tex]

So the number of dots tells us how many times we need to add the actual number underneath the dots. In conclusion, to find the mean you need to use both, the number of dots and the number underneath.
