What is experimental design?

Back

Experimental design is a structured approach to planning experiments that allows researchers to test hypotheses and determine cause-and-effect relationships.

What is a hypothesis?

Back

A hypothesis is an educated guess or prediction that can be tested through experimentation.

What is a dependent variable?

Back

The dependent variable is the factor that is measured in an experiment, which is affected by changes in the independent variable.

Front

What is an independent variable?

Back

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

Front

What is a control variable?

Back

Control variables are factors that are kept constant throughout an experiment to ensure that the results are valid.

Front

What is the purpose of a control group?

Back

The control group serves as a baseline to compare the effects of the independent variable in the experimental group.

Front

What is the difference between qualitative and quantitative data?

Back

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

Front

What is a sample size, and why is it important?

Back

Sample size refers to the number of subjects or observations in an experiment. A larger sample size increases the reliability of the results.

Front

What is randomization in experimental design?

Back

Randomization is the process of randomly assigning subjects to different groups to reduce bias and ensure that the groups are comparable.

Front

What is replication in experiments?

Back

Replication is the repetition of an experiment to confirm the results and ensure reliability.
