Frequency Polygons Card Complete Match In this activity

Frequency Polygons – Card Complete & Match In this activity students work individually or in groups to match questions and answers. ‘Quick Cut’ – Choose the questions/slides you wish to use and delete others. Sets of questions can then be easily guillotined to save time.

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’.

Match the data with a graph, then complete the frequency polygon. Calculate the median group from each set of data.
