??Which variable represent the independent? and dependent? ariables? ??Provide a? reason for your answer??? ?

The independent variable is the variable that is manipulated or controlled by the researcher, and the dependent variable is the variable that is measured or observed in response to changes in the independent variable.

For example, in a study looking at the effect of different study techniques on exam scores, the independent variable would be the study technique (e.g. flashcards, reading, practice tests) because it is being manipulated by the researcher. The dependent variable would be the exam scores because they are being measured in response to the different study techniques.

It is important to identify the independent and dependent variables in a study in order to understand the relationship between them and draw meaningful conclusions from the data.

Independent variable: Number of hours studied

Dependent variable: Test score

Reason: The number of hours studied is the variable that is being manipulated (the independent variable), and the test score is the variable that is being measured (the dependent variable). The test score is dependent on the number of hours studied.
