What is an independent variable?

Back

An independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

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

Front

What is a control group?

Back

A control group is a group in an experiment that does not receive the treatment or intervention, used as a benchmark to measure how the other tested groups do.

Front

What are constants in an experiment?

Back

Constants are the factors that remain unchanged throughout the experiment to ensure that the test results are valid.

Front

How do you formulate a hypothesis?

Back

A hypothesis is a testable statement that predicts the relationship between the independent and dependent variables.

Front

What is the purpose of an experiment?

Back

The purpose of an experiment is to test a hypothesis by manipulating variables and observing the outcomes.

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 the role of observation in scientific experiments?

Back

Observation is crucial in scientific experiments as it helps in gathering data and evidence to support or refute a hypothesis.

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 in an experiment.

Front

What is the difference between qualitative and quantitative data?

Back

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