1. Scatter Graphs – Card Complete & Match
In this activity students work individually or in groups to
match questions and answers.
Instead of cutting out cards, students can letter questions and
answers that go together.
A variety of card sizes are included.

2. Printing To print handouts from slides -
Select the slide from the left. Then click:
File > Print > ‘Print Current Slide’
To print multiple slides -
Click on a section title to highlight all those slides,
or press ‘Ctrl’ at the same time as selecting slides to
highlight more than one. Then click:
File > Print > ‘Print Selection’
To print double-sided handouts -
Highlight both slides before using ‘Print Selection’.
Choose ‘Print on Both Sides’ and ‘Flip on Short Edge’.

3. Match the data tables with the graphs.
Plot all the points on the scatter graphs.
Identify the coordinates of an outlier.
Plot a line of best fit.
Decide what type of correlation the scatter graph has.
