Is there a tremendous difference between control and variable data?

∙ 14y ago
A variable in a component to an scientific investigation in which the influence of its changing values and states are measured and recorded throughout the experiment. In other words a variable changes from trial to trial while a control stays the same throughout the experiment... If you are measuring the effect of light bulb wattage on plant growth then the number of watts would be the variable because one plant has 50w, another has 60w, and another has 100w. The controls would be that they all are the same distance away from the light bulb. Or that they are all the same type of plant. etc...

∙ 14y agoTremendous is a subjective and relative word. In most contexts where data will be statistically analyzed, the differencegenerated has to be greater than that produced by a randomized model, within a certain pre-determined tolerance, usually 5%. In other words, I ask the question: In a theoretical randomized experiment, would I get the results I actually obtained 5% of the time or less? If so, I can report significant results where p is less than or equal to 5 percent. There are some technical things you have to be careful about, like one-tailed or two-tailed tests, and other kinds of technical assumptions. These randomized results are built into various tables that can be used to perform the necessary tests; you don't have to actually do randomized trials. They are based on computer generated models. Depending on the research, an absolute research value may not seem to be very different from 'average', and still be quite significant; it depends only on how frequently your value would appear in the random model. Significance shouldn't be confused with correlation (Pearson's r, for example). For a correlation to have any kind of predictive strength (regression) the correlations have to be much stronger than 'significant'.

∙ 12y agothe difference is that variables have to do with science and controls are to switch channels on tv <-- guys an ass.

Why is it necessary to have an independent variable that is changed by the experimenter during an experiment?
The independent variable is changed by the experimenter so that the results can be compared to the control, which does not change. Any differences between the control and experimental group are due to the independent variable. cw: As written, you don't.
What is the variable that changes as a result of a scientist changing a variable?
It is a control variable.
What do you call the variable in an experiment that do not change?
Control Variable
What is the difference between speed and torque control?
Your question is wonderful .... But we are not intelligent enough to answer it ....
Variable that doesn't change in an experiment?
The variable in an experiment that remains the same is known as the control.
What is the difference between a control variable and a control treatment?
what is the difference between a variable and a control
What the difference between a variable and control?
The difference between a controlled variable and a variable is in their state. A controlled variable is something which is rigid and constant while a variable is liable to change and inconsistent.
What is the difference between a variable being tested and a variable being controlled?
The difference between these both is that the control is what stays the same in an experiment and the variable is what changes.
What is the difference between control and controlled variable?
control is when nothing is done to the experiment and controlled variable is that you have control over the experiment.
What is a the difference between a control and a variable?
A control is the standard to which an outcome of an experiment is compared, but a variable is something in an experiment that can change.
What is the difference between a variable and a control?
a control is a object that cant be changed in an experiment and a variable is a object that can be changed in a expirament
What is the difference between control and experimental variables?
Control Variable = kept in constant in a experiment Experimental Variable = changes in a experiment
What is the difference between an experimentation variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between an experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What are the difference between control set up and variable experimental set up?
The control variable is the thing you keep the same and is everything that is not the independent variable. The Control Setup is there for the sake of comparison.
What is the difference between variable air volume and volume control damper?
vav is volume control damper.. vav is variable air volume..
