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

And one from the hard end
A stem-and-leaf plot shows an outlier stem (one value in the 20s while most are in the 70s–90s). What argument could you make?
