Answer:
The independent variable is the calculator
The dependent variable is the speed of solving the problem.
The constant variable is the same set of problems that were assigned to two groups of students.
The dependent variable is the one that is being tested by experimentation. The dependent variable depends on the independent variable.
The independent variable can b changed by the experimenter whereas the constant variable remains unchanged throughout the experiment.
Answer:
Controlled Variable: The same math problems
Dependent Variable: The amount of time taken to answer
Independent Variable: One group using calculators and the other group not using calculators.
Explanation:
The dependent variable is the variable being tested and the independent variable is what is being changed. The controlled is what is staying the same.
