What is Experimental Design?

Back

Experimental Design is a method used to plan and conduct experiments in a way that ensures valid and reliable results. It involves identifying variables, creating a hypothesis, and determining how to test it.

What is an Independent Variable?

Back

An Independent Variable is the variable that is changed or manipulated in an experiment to observe its effect on the dependent variable.

Front

What is a Dependent Variable?

Back

A Dependent Variable is the variable that is measured in an experiment to see how it is affected by changes in the independent variable.

Front

What are Control Variables?

Back

Control Variables are the factors that are kept constant throughout an experiment to ensure that the results are due to the independent variable only.

Front

What are Trials in an Experiment?

Back

Trials refer to the number of times each level of the independent variable is tested in an experiment.

Front

What is a Hypothesis?

Back

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

Front

What is a Control Group?

Back

A Control Group is a group in an experiment that does not receive the treatment or independent variable, used for comparison.

Front

Why is it important to have multiple trials?

Back

Having multiple trials helps to ensure that the results are reliable and reduces the impact of random errors.

Front

What is the purpose of an experiment?

Back

The purpose of an experiment is to test a hypothesis by manipulating one variable and observing the effect on another.

Front

What is a Variable?

Back

A Variable is any factor, trait, or condition that can exist in differing amounts or types in an experiment.
