And here is the problem and plan which we wrote. (it was period 5 on a hot afternoon.)

Describing Scatterplots
You could also use your scatter plot to make predictions for the response variable by choosing a value for your explanatory variable.
Describing Dotplots and Boxplots
Class example on finding the mean, using a frequency table. To use a graphics calculator, use calc--> set to tell it to put the frequencies in list 2
Then you can enter the first column in list 1 and the frequencies in list 2
If you have grouped data, you can do almost the same thing, but you will have to find the midpoints of your groups to be your x-values or list1 values.
