Analyse data sets in stem-and-leaf plots and multiple-bar graphs, and make convincing arguments and informed decisions
30 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest, every one with a full worked solution. Work through all 30 with your weekly-lesson access code.
Sample: the first question, solved
A stem-and-leaf plot shows most leaves clustered on the stems 4 and 5 (representing the 40s and 50s). What can you conclude?
📘 Worked solution
✓Most values in the data set fall between 40 and 59, since that is where most leaves are clustered.
And one from the hard end
Two graphs compare the same data but use different scales: Graph A uses intervals of 5, Graph B uses intervals of 25. Why is checking the scale important before drawing conclusions?
