Front

What is a control group in an experiment?

Back

The control group is the group in an experiment that does not receive the treatment or independent variable, serving as a baseline for comparison.

Why is it important to have a control group in an experiment?

Back

A control group allows scientists to determine the effect of the independent variable by comparing it to a group that did not receive the treatment.

Front

What is the purpose of conducting experiments in science?

Back

The purpose of conducting experiments is to test hypotheses, gather data, and draw conclusions based on evidence.

Front

What does it mean to replicate an experiment?

Back

Replicating an experiment means conducting the same experiment multiple times to ensure that the results are consistent and reliable.

Front

What is a hypothesis?

Back

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

Front

What is the significance of randomization in experiments?

Back

Randomization helps eliminate bias by ensuring that each participant or subject has an equal chance of being assigned to any group.

Front

What is a variable in the context of an experiment?

Back

A variable is any factor, trait, or condition that can exist in differing amounts or types and can affect the outcome of an experiment.

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).
