Abbie Chapman · Answer 2

the control variable is the group that isn't using calculators as we're comparing the calculator group with the other. the dependent variable is the speed or time they take to do the integer problems as their time changes when using a calculator or not. the independent variable is whether they have calculators or not as it's a variation but it doesn't depend on any other variable.
