What would be the control, independent and dependent variable?

im doing an science experiment for science fair due in 2 weeks. my topic that im doing is, does it matter what colors are in a image in order to create a afterimage? How long does an afterimage last? How long does it take to occur? Im testing 10 different people, using the same images, each image is different in which the colors are different. So,... what would be my control, independent and dependent variable?|||Your control would have no color and see if there is an after image


Your independant variable is color


and the dependant variable is the afterimage... thats for just changing color.

What is the independent and dependent variable, control, and constant of this experiment?

Gatorade decides to create a new drink called "Energy" that they say gives people extra energy while running. To test this claim, they give 20 people the "Energy" drink before a mile run (they are Group A). They give 20 other people water before their mile run (call them Group B0.Group A runs the mile in 9 minutes while Group B takes 9.45 minutes.|||dependent variable = amount of energy


independent variable = time taken to run a mile


control = group B


constant = group B

What is the control group, independent variable, and the dependent variable in an experiment?

i have no idea what those things are.. here is an example of an experiment:


Smithers thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (in this case they're stapling). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, Smithers counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 2,113 stacks.


what is the control group?


independent variable?


and the dependent variable?|||Control group - Group B.


Independent variable - n/a


Dependent variable - how many stacks of paper

What would be the control variable for an experiment testing which type of bridge design is the strongest?

Please HELP! Thank YOu!|||Weight that is used to test the strength, before breaking.





Length, could be another. It has a min or a max length.





Another could be height.

In a scientific experiment, what is the control variable for?

Please help, i don't really get what it's for! Thanx in advance


xxx|||the control is used so that you have something to compare the results of your experiment to. The control is unchanged throughout the experiment.|||The control is for two things.





One, it will confirm that the experiment works as it should (e.g. in a bacterial experiment, a control can confirm sterility of the growth media).





Also, a control will give you the "zero response" if you use it for a calibration, in which case it is also known as a blank.|||control variables establish baselines. There are expected statistical results from the status quo %26amp; they should be accounted for prior to altering the test poulation.|||There are 3 variables which can be identified:


-manipulated variable: factors which are changed during experiment


-responding variable: factors that change according to changes in manipulated variable


-fixed variable: factors which does not change at all during experiment





In a scientific investigation, one variable is manipulated to study its relationship with a responding variable.

What's a Constant and a Control Variable ?

Whats the dfffrence between a constant and a control variable ? Please show examples [:|||er i thought they were the same thing

True or false if you do not control variables in an experiment there will be no way to know which variable exp?

True|||Yeah, you forgot to finish your question, but I can tell you that the answer is false. Multiple regression techniques make it possible to determine the importance of each variable without holding one constant.|||I think you forgot to finish the question here.
