Experimental Design and Variables

Front

What is an independent variable?

Back

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

Front

What is a dependent variable?

Back

The dependent variable is the factor that is measured or observed in an experiment to see how it is affected by changes in the independent variable.

Front

What are constants in an experiment?

Back

Constants are the factors that are kept the same throughout an experiment to ensure that the results are valid.

Front

What is the purpose of a control group?

Back

A control group is used as a standard for comparison in an experiment. It does not receive the experimental treatment.

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, temperature).

Front

What is a hypothesis?

Back

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

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

Front

What is an experiment?

Back

An experiment is a structured procedure carried out to investigate a hypothesis by manipulating variables and observing the outcomes.

Front

What is the role of replication in experiments?

Back

Replication involves repeating an experiment to verify results and ensure reliability.

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.
