In an experiment designed to measure the distance a golf ball is hit by clubs made of different material, a standardized variable would be:
A The distance the golf ball traveled
B The type of material the club is made of
C The material the golf ball was made of
D The wind direction when the experiment took place
E Both the wind direction when the experiment took place and the material the golf ball was made of are correct
I think it is b but for some reason I am thinking it may be wrong.
If by "standardized variable" you mean the variables that need to be controlled, E is the answer. A is the dependent variable and B is the independent variable.
An independent variable is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable.
A dependent variable is the response or measure of results.
Extraneous variables — other than the independent variable — potentially can affect the dependent variable, so they must be controlled. If possible, you try to keep them constant between the experimental and control group.
The experimental group receives the independent variable.
The control group is similar to experimental, except it does not receive the independent variable. Extraneous variables are balanced between experimental and control groups.
