Med Det: Experimental Design

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the variable that responds to the experiment and is measured to determine if the hypothesis is true.

Front

In the context of experimental design, what is a hypothesis?

Back

A hypothesis is a testable statement predicting the relationship between the independent and dependent variables.

Front

What is the purpose of a control group in an experiment?

Back

The control group is used for comparisons to determine the effect of the independent variable.

Front

What is an independent variable?

Back

The independent variable is the variable that is manipulated or changed in an experiment to observe its effect on the dependent variable.

Front

Define 'conclusion' in the context of an experiment.

Back

A conclusion is a summary of the experiment that includes whether the hypothesis was supported or not.

Front

What is the significance of replicating an experiment?

Back

Replicating an experiment increases the reliability of the results and helps confirm the findings.

Front

What is a variable in an experiment?

Back

A variable is any factor, trait, or condition that can exist in differing amounts or types.

Front

How does one determine the dependent variable in an experiment?

Back

The dependent variable is determined by identifying what is being measured or observed in response to changes in the independent variable.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities, while quantitative data involves numerical measurements.

Front

Why is it important to control variables in an experiment?

Back

Controlling variables is important to ensure that the results are due to the independent variable and not other factors.
