Predict and test whether the mean, median, 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's mean score is 80. Would you expect Class B (a similar-sized class) to have a mean score close to 80?
📘 Worked solution
✓Yes, it's reasonable to predict a similar mean, though it's not guaranteed.
And one from the hard end
An existing class of 20 students has mean=70, median=72, mode=75. Predict all three for a new same-sized class, describe how you'd test all three, and explain what counts as "fully confirming" versus "partially confirming" the prediction.
