What variables don't change in an experiment?

In an experiment, the variables that do not change are called constants or control variables. These are aspects of the experiment that are kept consistent and not altered, providing a baseline for comparison with the variable being tested. By controlling these factors, researchers can isolate the effects of the variable they are studying.

What is the host group in an experiment?

They are used as a baseline for comparison against the groups that do receive the treatment, helping researchers determine the effects of the treatment by comparing it to a control group.


What is make an experiment a controlled experament?

A controlled experiment is one in which all variables except the one being tested are kept constant or controlled. This allows researchers to accurately measure the impact of the variable being tested on the outcome of the experiment. By controlling for other factors, researchers can isolate the effects of the specific variable they are interested in studying.

What is a control in earth science?

In earth science, a control is an experimental element that remains constant or unchanged throughout an experiment. Controls are used to compare results and determine the impact of specific variables being tested. By keeping certain factors constant, scientists can isolate the effects of the variables they are studying.


Why is an experiment called a controlled study?

An experiment is called a controlled study because it involves manipulating variables under controlled conditions to isolate the effects of those variables on the outcome or results. By controlling other factors that could influence the results, researchers can more accurately determine the impact of the variables they are studying.

Can an experiment have more than one dependent variable?

Yes, an experiment can have more than one dependent variable. This may be necessary when studying the effects of an intervention or treatment on multiple outcomes or behaviors. Researchers need to carefully consider how each dependent variable is related to the independent variable and how they will measure and analyze these relationships.
