There are three types.Explain the meaning of them:MeanMedianModeWhen would be a bad time to use the mean?When would be a bad time use the median?When would be a bad time to use the mode?Results need to be shown graphically in a table, a bar chart or a line graph. Tick if you know whatthose are. Cross if you don’t.
