Rachel divides 100 people into two groups based upon their self-esteem scores from a previous psychological test. She administers a math test to the two groups and compares their scores.|||Independent variable is the self esteem score value of interest. Certain scores place people in the test group while other scores place them in the control group. The control are people who undergo the math test but do not have the self esteem quality being examined as impacting the test results. One is the test group one is the paired control group.
dependent variable are the resulting scores

What is the dependent variable and control of this experiment?
i am testing between two pieces of chalk, one is brown and one is white, and the question is which one will last longer on a board.|||The independent variable is the type of chalk, the dependent variable can be either the total length of the line produced on the blackboard or the amount of time it takes to use up the chalk given equal usage. It depends upon how you set up your experiment.
Honestly I haven't a clue as to how one would set up a control for this.

What is the control, experimental variable, responding variable, experimental error, and a conclusion?
a randomly selected group of 1, 092 students were chosen taste a new and improved formulation of sour cream and onion potato chips. Each student ate 15ounces of potato chips. Of the 563 students that were given a new formulation of sour cream and onion potato chips, 89 developed cramps from gas. Of the 529 students that ate the old formulation of sour cream and onion potato chips, 111 developed cramps?|||a randomly selected group of 1, 092 students were chosen

Control and constant variable for a science project?
My problem statement is how accurate are eyewitnesses testimonies?
I basically played out three scenarios and gave them a test on what they remember
my independent variable- The three scenarios
Dependent- How accurate their observations were.
what the he!! are my control and constant?
|||It sounds cool but the problem you are having is because it wasn't really an experiment. There was no hypothesis. It was just an observation.
To make an experiment out of it, you have to have two or more groups observing different things, the characteristics of which, you control. You can be testing anything, but whatever the factor you are testing, that will be your dependent variable. The conditions you set would be the independent variables. I'll give you an example.
Let's say you're testing the accuracy of a person's responses on the basis of stress. You have two scenarios; one which is pleasant and non-stressful and one which is frightening or disturbing. Then you ask two groups of observers the same kinds of questions about each. This can be tricky to set up because of the number of factors you might overlook. But at least now it is an experiment. The control, or independent variable would be stress. Notice, in your present observation, you have no such variable that you are testing.
So you would look at the scores. The more participants, the better. If you tested 20 people and they scored on average, 30% better on the pleasant observation test, then you might have demonstrated a clear relationship.
I mention this example because this very experiment has been clinically conducted many times and it has been shown that there is a clear correlation between the stress level of the observer and the inaccuracy of their answers to questions about it. This has become a precedent in many court cases.
Good luck and have fun. A warning about ethics: do not make your stressful scenario too disturbing. Have it just be an argument or something: no fake gore or anything like that, (even though bloodshed is a SURE FIRE way to blow people's memories all to hell. Don't do it.)
Edit: another thing. Your subjects should not know or even suspect what your experiment is really about. If they know, then the experiment becomes invalid because that would have been a necessary control.
E-mail me if you would like to impress you teacher by double-blinding your experiment. I'll tell you how to do it. That's an important control, too.

What is the difference between an independant variable, dependant variable and control?
You are asking about a closed-loop control system, for those terms to be applicable.
The independent variable is the input to the control system, basically, a setpoint change, or a load change, aka, disturbance.
The dependent variable is any output of the control system, i.e. flow, temperature, pressure, level, etc.
The control variable is the dependent variable right after the controller, into the control element, ie, flow control valve, heater, etc.|||indpent varible: this one is x: the varible you can change (ie: amount of sunlight)
depent varible: this one is y: the varbile you can't change (ie: time)
control, aka constent: stays the same throught out the expirment
example: say you want to seee if different colour light a/effects the way ablino corn grows.
control: corn
d. v.: time it takes to grow
i. v.: colour light
*you compare the iv to the constant!*
*you can't change the dv by laws of science*
HOPE THIS HELPED!|||The independent variable is the one you are changing. The dependent variable is the one that you don't change.
For example, you are testing the growth of a plant based on the amount of water.
The dependent variable would be the growth (you're not physically changing it) and the amount of water would be the independent variable (you are going to put a different amount of water in each pot).
A way to remember it is: DRY MIX. (dependent, responding, y), (manipulative, independent, x)
The control is one that is neutral to ensure that there are no hidden variables.|||ok, I know nothing about control but I do know about Independant and dependant variable.
Dependant Variable.
when two variables are dependant, it means that the change of one affects the other.
The variables affect each other. The variables are related to each other.
what happens to one variable depends on the other and vice versa
Independant variables.
variables are Not related to each other.
It doesn't matter what happens to one variable because it will not affect the other variable.|||Independent is always on the X axis
Dependant is always on the Y axis
The dependent changes due to the independent, so when the independent is altered the dependant changes
Control is like if you have a graph that shows like you had 10 plants and each plant u gave a certain amount of water and you wrote down how much each grew, the control group would be the plant that didnt get any water.|||independant variable- (normally x) does not depend on the other variable
dependant variable- (normally y) is the way it is b/c of the other variable
control- no idea

Whats a variable and a control?
am doing this science project where i planted marigolds and then put different types of water.whats the variable and the control?|||a control stays the same
and a variable you do something different too
ex- the control gets regular water and the variable gets water w. sugar or water w. miracle grow.

Science Experiments that involve variable and control?!?!?
I need a science experiment for highschool students that involves a variable and control. I need to write a method paper on it so I want something creative. I searched everywhere and I just can't find anything! Please help! Thanks.|||Hi,
My daughter had to do one like this, and since it is Spring, she did plant seeds.
She planted bean plants in several cups. The variables were (1) amount of water, (2) amount of fertilizer, (3) amount of light. Then she measured the growth of the plants over time, carefully controlling different variables in each cup.
Just a thought. :-) Good luck!|||These sites have or point to lots of science fair project ideas:
