What is the difference between qualitative and quantitative data?

Back

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

Front

What is a hypothesis?

Back

A hypothesis is a testable prediction about the relationship between two or more variables in an experiment.

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or manipulated by the experimenter to observe its effect on the dependent variable.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in response to changes in the independent variable.
