Predict and test whether the mean and mode(s) of a data set from one population will be the same for a different population
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
Class A (20 students): mean test score=75, mode=80. Predict whether Class B (20 students) will show similar values.
📘 Worked solution
✓It's reasonable to predict similar values, since similar-sized groups often show similar patterns - but this isn't guaranteed.
And one from the hard end
An existing class of 24 students has a mean of 65 and a mode of 60 for test scores. A new same-sized class's actual mean turns out to be 66 and actual mode turns out to be 70. Which statement best evaluates both predictions together?
