Experimental Control and Variable?

What is the difference of control and variable in a experimental?Experimental Control and Variable?
The experimental control is just another way to say control set-up. Basically it is the set-up where the manipulated variable is not present or is a basis. (Like just plain water for growing plants)





The Experimental variable is also known as the manipulated variable, and is the actual variable that you manipulate in your experiment. (Like 5% Fertilizer water vs 10% Fertilizer water for growing plants)Experimental Control and Variable?
In any kind of experimental study, you need to first have a hypothesis, an expected experimental outcome or result. Next, you need to know what the variables are that influence your expected findings. Then, if possible, you want to be able to set your experiment up in such fashion that you can hold all of the variables constant except for the one that you are interested in. You then proceed to test each variable over a range of conditions while holding all other variables constant. You compare your findings with a ';control'; that is not tested under experimental conditions. In this way, you can compare your experimental data with a known standard in order to determine if your experimental findings fits with your expected results.





From that, you can do some type of analysis of the data.
You have 50 mice.


You want to know if giving mice extra vitamins makes them live longer. Longer that what? Answer: Longer than mice that don't get extra vitamins.


So in your experiment, you give 25 mice extra vitamins, and the other 25 mice eat a normal diet without extra vitamins. The first group is your variable group. This last group of 25 mice is your control group.
