Is there a tremendous difference between control and variable data?

Answer 1

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...

Answer 2

Tremendous 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'.

Answer 3

Yes, there is a significant difference between control and variable data. Control data refers to a constant value used as a reference or baseline, while variable data can vary over time or across different scenarios. Control data is often used to compare and analyze changes in variable data under different conditions.

Answer 4

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