Collect data on two pieces of information, and organize it in two-way tally tables
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
You want to survey classmates on favorite pet (dog/cat) AND favorite subject (math/art). What should the table's rows and columns be?
And one from the hard end
A two-way tally table has 4 cells summing to 20 students, sorted by "likes sports" (yes/no) and "has a pet" (yes/no). If "sports+pet"=8, "sports+no pet"=5, and "no sports+pet"=4, find the last cell ("no sports+no pet") and verify the total.
