RESEARCH METHODOLOGY

Detailed explanation-1: -The test scores would be the dependent variable and the amount of studying would be the independent variable.

Detailed explanation-2: -What is a dependent variable? A dependent variable is the variable that changes as a result of the independent variable manipulation. It’s the outcome you’re interested in measuring, and it “depends” on your independent variable.

Detailed explanation-3: -The scientific method is the process of objectively establishing facts through testing and experimentation. The basic process involves making an observation, forming a hypothesis, making a prediction, conducting an experiment and finally analyzing the results.

Detailed explanation-4: -Example: a car going down different surfaces. Independent variable: the surface of the slope rug, bubble wrap and wood. Dependent variable: the time it takes for the car to go down the slope. Controlled variable: the height of the slope, the car, the unit of time e.g. minutes and the length of the slope.
