Question

in the scenarios below, identify the independent variables, dependent variables and control or constants.

1. three groups of students are given study outlines for 6 weeks. one group studies 2 hours a night, a second group studies 1 hour a night, and the third group only studies 30 minutes. their final exam grade will be at the end of the 6 weeks.

independent-
dependent-
control/constant-

Explanation:

Step1: Define independent variable

The independent variable is what is being changed or manipulated. Here, the amount of study - time per night is different for each group (2 hours, 1 hour, 30 minutes). So, the independent variable is the number of study - hours per night.

Step2: Define dependent variable

The dependent variable is the outcome that is being measured. In this case, it is the final exam grade at the end of 6 weeks.

Step3: Define control/constant

The control or constants are the factors that are kept the same for all groups. Here, all groups are given study outlines for 6 weeks. So, the study outlines and the time - period of 6 weeks are the control/constants.

Answer:

Independent - The number of study - hours per night
Dependent - The final exam grade
Control/constant - The study outlines, the 6 - week time period
