What is Experimental Design?

Back

Experimental design is the process of planning an experiment to ensure that it can effectively test a hypothesis. It involves selecting variables, determining how to control them, and deciding how to collect and analyze data.

What is a Controlled Experiment?

Back

A controlled experiment is a scientific test where one variable is changed while all others are kept constant to isolate the effects of the variable being tested.

What is an Independent Variable?

Back

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

Front

What is a Dependent Variable?

Back

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

What is a Control Group?

Back

The control group is the group in an experiment that does not receive the experimental treatment and is used as a benchmark to measure how the other tested subjects do.

What is an Experimental Group?

Back

The experimental group is the group in an experiment that receives the treatment or condition being tested.

Why is Replication important in experiments?

Back

Replication is important because it allows scientists to verify results by repeating the experiment under the same conditions to see if they obtain the same outcomes.

Front

What is a Hypothesis?

Back

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

What is the purpose of a Scientific Journal?

Back

A scientific journal is a publication that disseminates research findings to the scientific community, allowing for peer review and validation of results.

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.
