The independent variable, dependent variable, and controlled variable will be the presence or absence of a calculator, speed working with problems, and the problems given to be solved respectively:
- Independent variable: In a given study, the variable which is not affected by any other present or given factor/variable is known as an independent variable.
- In this case, the presence or absence of a calculator acts as the independent variable as it is not influenced by any other variable.
- Dependent variable: In a given study, the variable that depends or changes when a change occurs in another variable, preferably the independent variable, is called the dependent variable.
- In this case, the speed of working the problems depends on the availability of the calculator, thus it is a dependent variable.
- Controlled variable: It is a type of variable that remains the same/constant throughout the study even on changing different variables.
- In this case, in both types of situations, the same set of problems is provided, thus it acts as the controlled variable.
