True or false. the control subject of an experiment be exposed to all variables?
False. The control subject (Or control group) should be kept isolated from the variables of the experiment. This group will detemine if changing a variable is better or worse than not changing the variable.
Why is it important to test only one variable at a time during a science investigation?
If you test only one variable then you know that the difference in the experimental and control setup is that one independent variable. If you test more than one you will not know which one made the difference.
What are the constants and control related to science?
A constant is the thing that stays the same. The control is the normal variable or the regular variable. The control will help, in a science experiment, to see if a new object works better than the regular one. The constants helps to keep the experiment fair.
Why is only one variable changed in an experiment?
You can have more than one variable, but it would take longer to solve.
Why should an experiment be tested only one variable at a time?
if you change more than one variable, you will not know which one has had an effect on the experiment. If the outcome changes when one variable is altered, then the change can only be due to the one variable, by logical deduction.
Does the experimental group test the dependent variable?
Yes, the experimental group is typically the group that receives the treatment or intervention being tested, and this treatment is what may cause changes in the dependent variable.
True or false. the control subject of an experiment be exposed to all variables?
False. The control subject (Or control group) should be kept isolated from the variables of the experiment. This group will detemine if changing a variable is better or worse than not changing the variable.
Why can't you test more than one variable in an experiment?
you can't because you will not have the right results to the experiment.In order to make sure you are getting good results from an experiment you should conduct repeated trials, use only one control group, have as many individuals as possible in both the control group and the experimental group, and test only one independent variable at a time.Hope that helped!
Can you have more than one variable?
Yes, you can have more than one variable
Can an expression have more than one variable?
Yes, an expression can have more than one variable.
What is the difference between an HtmlInputCheckBox control and an HtmlInputRadioButton control?
You can select more than one HtmlInputCheckBox control from a group of HtmlInputCheckBox controls; whereas, you can select only a single HtmllnputRadioButton control from a group ofHtmlInputRadioButton controls.
What is the variable of 5 more than s?
The variable of 5 more than s is s + 5.
What is the term for an equation with more than variable?
An equation with more than one variable is called a multivariate equation.

What is the energy savings of an electric motor when reducing the speed with a variable frequency drive?
definitly it give more efficient than variable stator voltage.............but in variable frequency ...............the frequency is not only variable....it is E/F control.because to maintain constant flux......... USUALLY THIS SPEED CONTROL IS ODOPTING IN INDUSTRIES......
Can a experiment have more than one independent variable?
yes it can I've done a few experiments that have had more than one independant variable.
