Average and spread (mean, median, mode and range)

An interactive geogebra applet that models the how to calculate average and spread of a data set including…

==> Mean, median, mode and range from a list of numbers
==> Reverse average problem solving
==> Combining mean problems
==> Mean from an ungrouped frequency table
==> Median from an ungrouped frequency table
==> Interquatrile range from an ungrouped frequency table
==> Estimate of the mean from a grouped frequency table
==> Estimate of the median from a grouped frequency table
==> Estimate of the interquartile range from a grouped frequency table

The applet generates progressively differentiated examples for modeling with your class. Please see the video for how the use the teaching aid. I have also included a set of differentiated worksheets with solutions. These are also previewed in the video.

The geogebra applet is attached but if you don’t have it installed then the web link is also attached so you can use the applet in any web browser.
