What is Experimental Design?

Back

Experimental design is the process of planning an experiment to ensure that it can effectively test a hypothesis by controlling variables and collecting data.

What is an Independent Variable?

Back

An independent variable is the factor that is manipulated or changed in an experiment to observe its effect 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 to assess the effect of the independent variable.

Front

What is a Control in an Experiment?

Back

A control is a standard for comparison in an experiment, which is not exposed to the independent variable.

Front

What are Constants in an Experiment?

Back

Constants are the factors that remain unchanged throughout the experiment to ensure that the results are due to the independent variable.

Front

What is a Hypothesis?

Back

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

Front

What is the Purpose of Data Analysis in an Experiment?

Back

Data analysis involves organizing and interpreting the collected data to draw conclusions and determine if the hypothesis is supported.

Front

What is the Importance of Replication in Experiments?

Back

Replication is important because it allows for verification of results and ensures that findings are reliable and not due to chance.

Front

What is a Testable Question?

Back

A testable question is a question that can be answered through experimentation and observation.

Front

What is the Role of a Conclusion in an Experiment?

Back

The conclusion summarizes the findings of the experiment, discusses whether the hypothesis was supported, and suggests further research.
