10 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest — every one with a full worked solution. Work through them free, no account needed.
Sample: the first question, solved
Class A (20 students): mean test score=75, mode=80. Predict whether Class B (20 students) will show similar values.
📘 Worked solution

And one from the hard end
Class J's actual data set is 5, 5, 8, 10, 5, 12. What is the actual mode?
