Mean, Mode, Median, Range.

This PowerPoint of 22 slides introduces the four measures of Mean, Mode, Median and Range. Explaining the calculation or recognition of each measure and the advantages or disadvantages of each, with examples that demonstrate these features. Also, the measures each have questions for students to answer, therefore consolidating their learning before moving on to the next measure. Slides 19 to 21 have questions for which all four measures need to be calculated. The last slide has 3 number lines that I used in creating the earlier examples, these have adjustable markers so can be used to display any data or question that you may wish to add.
