A scientist would need to identify variables so you could know what to change and what to keep the same. A scientist would need to control variables so you can try to see exactly which factors are affecting the dependent variable (the thing you're measuring). Hope this helped! Because I have the exact same question on my homework!
What else can I help you with?
Why do scientists try to control most variables in an experiment or observational study?
To make "the most correctable solution"
It is important to control variables in an experiment because?
in an experiment cantrolling variable is important as it helps to identify the limiting factors are present in the experiment, and also factor that do not necessarily affect the experiment.
What is purpose of having a control in a experiment?
Having a control in an experiment allows you to see what happens when no variables are changed. If you do not have a control, you do not have anything to compare your results with after changing variables of the experiment.
To ensure that an experiment is testing only one variable scientists often run a?
controlled experiment where all variables are kept constant except for the one being tested.
Can a variable affect the results in an experiment?
Yes, variables can affect the results of an experiment by introducing bias or influencing the outcome. It is important to identify and control for variables to ensure the reliability and validity of the experiment's results.
What are the variables that are not changed in an experiment?
In an experiment, variables that are not changed are called control variables. These variables are kept constant to ensure that any changes observed in the experiment are due to the manipulated variable, or independent variable, and not due to other factors.
Is it easier to control dependent variables than independent variables in a scientific experiment?
It is easier to control independent variables
Variables that do not change in a experiment?
the dependant variable
Identify the variables that you need to control and the variable that you will change?
To conduct a controlled experiment, you need to control all variables except the one you are changing. The variable you change is called the independent variable, and the variable you measure in response is the dependent variable. Control variables are those that could potentially affect the outcome of the experiment but are kept constant to isolate the effect of the independent variable.
What is control varieble?
The Variables That do not change in the experiment
Why must scientist control variables in their experiments?
An experiment is a simulation of complete or part of a real scenario in a controlled environment. We come to know of various outcomes of an experiment based on the values/degree of the variables in different quantity/quality. Unless the variables are controlled, experiment can go out of hand and sometimes become a real disaster.
