What is the difference between experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What conditions must be met if you want to have a scientifically valid sample for a study?
You must have a control group, an experimental group, an experimental variable (also called the independent variable), and a response to be measured (also called the dependent variable). The experimental variable is applied only to the experimental group, so that any difference between the control group and experimental group is due only to the experimental variable. Both the control group and experimental group must have the same conditions, except for the experimental variable.
What type of a variable is an experimental controls?
independent variable
In an experiment the group that is exposed to the variable to be tested is called the?
control group
In an experimental design the variable the researcher has control over and that is different for the treatment and control groups is called the?
Explanatory variable apex
What type variable is an experimental control?
Independent variable
What type of variables is experimental control?
Independent variable
Which term describes a type of independent variable used to compare differences in dependent varables?
experimental control

What is the difference between control and experimental variables?
Control Variable = kept in constant in a experiment Experimental Variable = changes in a experiment
Why is a control group important to have in a experiment?
A control group is the standard of comparison between what happens with the experimental variable and without the experimental variable.

What do you call an experimental setup in which the experimental variable is missing?
control setup
Why is experimental control needed in experiments?
The experimental control is what you compare your experimental data with. Without the control, you can't tell if the variable you are testing is what is causing your results.
