There's no "Limit", but the less you have, the better the experiment.

What are the experimental variables?

Experimental variables are factors being tested or measured in a scientific experiment. They can be categorized as independent variables (manipulated by the experimenter), dependent variables (respond to the changes in the independent variable), and controlled variables (kept constant to prevent interference).


What is the difference between control and experimental variables?

Control variables are kept constant throughout an experiment to ensure that any changes in the dependent variable are due to the manipulation of the independent variable. Experimental variables, on the other hand, are the factors that are deliberately changed by the researcher to observe their effect on the dependent variable.


How many variables can be tested at a time?

An experiment should test only one variable (the independent variable) at a time. If you are testing more than one variable at a time, you have no idea which variable is causing which effect.


Variables that are always different between the experimental and the control groups are?

Independent variables. If the treatment has no effect , the dependent variables for both the control and experimental group may be the same. cw: In some studies, there is no specific control group. For instance, in a drug study where subjects are given a random amount of the drug (from 0 up to some presumed safe level) then you cannot easily tell what the "experimental" group is -- you can't compare everyone else to the two subjects who got a placebo (0 mg/kg). You can tell whether the treatment is having a linear effect, etc.


How many variables should there be in a good experiment?

There should be one dependent variables. Depending on the type of research you are doing, the amount of independent variables will change. If you are doing research on a large scale, you will use more independent variables. If it's on a small scale, you will use very little. If you are not able to run your regression it means your sample size is too small or you have too many independent variables.

Yes. If you have too many variables, you cannot be sure what caused the results.

What should an experimental design frame look like?

An experimental design framework typically includes a clear statement of the research question, a detailed description of the experimental procedures to be followed, identification of the variables to be manipulated and measured, a hypothesis to be tested, and a plan for statistical analysis of the data collected. It should also include information on the control group, randomization, and any potential confounding variables that need to be addressed.
