hey! the IV of the experiment is retention intervals and if you also look for the interference then you may set 4 blocks , in that case you can see the forgettin rate of first and last block. so 2ND Iv is blocks. dv: recall accuracy ;)
Salivation was a learned response
The manipulated/independent variable is a variable that changes and it is what the responding/dependent variable change because of the manipulated variable.
In an experiment with frogs, no, the age of the frog is not a control variable. Instead it is an independent variable,or something you change.
The following is a hypothesis: "The number of eggs a chicken lays is affected by the hours of daylight." In this hypothesis, the independent variable is the hours of daylight.

The independent variable is the brand. The dependent variable is how absorbent it is. There may be other variables such as temperature, but I doubt different brands of paper towels absorb different amounts of heat or have different specific heats. There are crap tons of variables you probably don't have to worry about, because they're probably not that "variating" anyway.
That's the independent variable.
Its existence is the only independent variable. Anything else depends on the context of the study.
An independent variable is the factor that is manipulated by the experimenter in an effort to study the effects of the change upon the dependent variable.
The answer depends on the context of the study.
It can depend on nothing or on an variable which is outside of the scope of the study.

The independent variable is the thing you are changing. The dependent variable is the result you are trying to measure. In a caffeine study, the amount of caffeine given to a subject would probably be the independent variable. The dependent variable would be what you are measuring, like moodiness, apparent energy, kidney function, etc.
The type of tread is the independent variable and the braking distance is the dependent variable.
independent variable dependant variable constants
the experimental group is exposed to the independent variable (X), then observations of the dependent variable (O) are made. No observations are made before the independent variable is introduced.
na
yea losertttttt actually, it is the independent variable because the independent variable is the thing that you change and the dependent variable is the outcome whoever doesn't know this, I'm sorry, but now you know.
