A lesson that outlines all the different types of data. When it is best to use each type and whether these types of data would be considered valid/reliable?
A lesson covering the methods used for finding the different types of averages and the range for un-grouped data. The lesson then goes on the cover more problem solving questions that require students to work backwards with the averages to work out the missing data. Or methods for using reverse mean.
A whole lesson focused around producing histograms, analyzing and interpreting histograms and finding missing data. Opportunities for deliberate practice.
