- Definition
Two-variable data means you've collected two different pieces of information about the same thing or person, like their height and their age, to see if there's a connection between them.
Tracking the number of hours a student studies and the grade they get on a test is collecting two-variable data.
How to teach this in 30 seconds
Try this analogy: Two-variable data is like asking each of your friends two questions, like 'how many hours did you study?' and 'what was your test score?', to see if there's a connection.
Ask your child: What two things could we measure about your friends to see if they're connected?
Common mix-up: Kids may think you're just comparing two separate lists of numbers. The key is that each pair of data points, like height and shoe size, comes from the same person.
Examples
- Recording the daily high temperature and the number of ice cream cones a shop sells that day.
- Measuring a plant's height each week and also counting the number of leaves it has.
two-variable data is a term used in Ontario’s Kindergarten to Grade 8 curriculum.
