An interactive geogebra applet that aids the modeling of drawing and interpreting histograms. Includes equal class widths (normal bar charts) and unqual class widths (histograms). Please see the video for how the use the teaching aid. I have also included two scaffolded worksheets. One for reading and interpreting histograms and one for estimating quartiles and percentiles as seen in A-Level and GCSE specs.
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.
