no a variable is anything that can change. a result is what you conclude after performing an experiment.
example:
ok let's say you want to test a new fertilizer you would most likely use two different plants in the same room using a different fertilizer for each plant. the variable would be the fertilizer and the result would be if the new fertilizer worked or not.
hope this helps.
dependent variable
The independent variable is the thing that stays the same throughout the problem.
That will result in "replications" of the experiment.
Since the variable is the same, you can use the distributive property for this one. That is, subtract -8 minus 4, and attach the variable, "x", to the result.
In my humble opinion, what people mean with a statistical variable is the same as a random variable, which is explained well in wikipedia: http://en.wikipedia.org/wiki/Random_variable.
The manipulated variable is the variable that is changed in the experiment. The responding variable is the result of changing the manipulative variable, and the controlled variable is the variable that's stays the same throughout the entire experiment.
Two expressions are "equivalent" if they have the same result for any values of the variable or variables.
A variable means that something that you can change, measure, or keep the same. Example: Responding variable: The variable you can measure. Controlled variable: The variable you keep the same. Manipulated variable: The variable that you change.
the same
something that changes and doesn't stay the same a variable is something that you change
A variable within an experiment that remains the same. Such as the weight of a pendulum.
The three variables of a science project are: 1. Controlled variable: A controlled variable means the part of the experiment that stays the same. This is also called the dependent variable. 2. Manipulated variable: A manipulated variable is something that can be changed by the experimenter. Also known as the independent variable. 3. Responding variable: A responding variable is the variable which you have to measure to get your results. So, you do not know the values of this variable until you measure it.

the control variable is the same
It would mean that the result was 2 standard deviations above the mean. Depending on the distribution of the variable, it may be possible to attach a probability to this, or more extreme, observations.It would mean that the result was 2 standard deviations above the mean.
