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

What are the experimental variables?
Expirimental Variables The part of your expiriment that does not change.
What is the difference between control and experimental variables?
Control Variable = kept in constant in a experiment Experimental Variable = changes in a experiment
What is the constant variable in investigation of fungi growth mold?
The variables that you keep the same between the control and experimental groups are the constant variables.
How many variables should you have when you test a hypothesis?
there should be atleast 1
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 be tested on the experimental group in an experiment?
Just one at a time
How many variables are tested during an experiment?
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
What is used as a way to compare values for a dependent variables in many experiments?
experimental control
Can too many variables lead to greater experimental error?
Yes. If you have too many variables, you cannot be sure what caused the results.
How many variables are kept constant in a experiment?
All variables except one, the experimental variable, are kept constant in an experiment.
What are the experimental variables?
Expirimental Variables The part of your expiriment that does not change.
Factors that are varied during an experimental procedure are called?
Variables
What is used as way to compare values for dependant variables in many experiments?
experimental control
What is used in a way to compare values for dependent variables in many experiment?
experimental control
What is experimental grouping?
experimental group or set ups with same variables. OMG i hate scince
What are experimental variables?
things that you change every trial
What type of variables is experimental control?
Independent variable
