A hypothesis is a testable prediction about the relationship between the independent and dependent variables.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities (e.g., color, texture), while quantitative data involves numerical measurements (e.g., height, weight).

Front

What is an example of a dependent variable in a driving skill study?

Back

Skill of driving is an example of a dependent variable, as it is measured to see how it is affected by the independent variable (age of students).

Front

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

Back

The control group serves as a baseline to compare the effects of the independent variable, helping to validate the results.

Front

How do you identify the independent variable in an experiment?

Back

The independent variable is identified as the factor that is intentionally changed or manipulated by the experimenter.

Front

What is the significance of measuring the distance to stop in a car experiment?

Back

Measuring the distance to stop helps determine the effect of different types of cars on braking performance.
