Answer:
"Independent Variable: Use of calculators
Dependent Variable: How fast student worked math problem
Control: Group not using calculators
Constant: Same math problem"
Explanation:
Independent variable: In research, the term "independent variable" is described as a variable that is being changed by a researcher to see its effects on the dependent variable. Independent variable isn't changed by any variable a researcher is trying to evaluate or measure.
Dependent variable: It is being tested by the researcher, and tends to represent a specific quantity whose value is dependent on some manipulations i.e., any changes being made onto the independent variable will hamper the dependent variable directly.
Control group: It is composed of specific participants that don't receive the "experimental treatment". When a researcher is administering an experiment, these participants are being randomly assigned to the given group.
