the variable
The number of dependent variables in an experiment varies, but there is often more than one. experiments also have controlled variables are quantities that a scientist wants to remain constant, and he must be observe them as carefully as the dependent variables.
Variable is, logically, something that varies, that is to say, is not constant over time. Controlled variable, in the control field theory, is a variable measure that is, or that needs to be, controlled. Like a voltage that you need to keep under 10Volts because some devices in the setup have an amplitude limitation. Manipulated variable is usually a measure, a variable that you can measure. For example, if you can measure the voltage in the experimental setup then you can manipulate it, like using it to power a device. Constant variable, i think this is not very correct, a mathematician's opinion might be needed. For me is a variable, thus something that is variable over time, that under certain conditions becomes constant, thus stops varying according to time.
It varies depending on the glass, but about 2.6 grams.
To be more sure of their results. Say you are testing the effects of aspirin on heart disease. If you only tested two people (one that got aspirin and one that got a placebo) there are an enormous number of reasons why the two people could be different BESIDES getting aspirin or placebo. If you tested 1000 that got aspirin and 1000 that got placebo and the two groups differed, it should be because of the aspirin (the other possible explanations should cancel-out in such a large sample, why would all the people with the worst heart health or all the men end-up in one group?). The larger the "sample size" the more sure we will be that the effect was actually due to the aspirin. This also enables us to look not at the effect of aspirin on an individual (something that is very unstable and varies a lot from person to person) but the effect of aspirin on a GROUP. An effect that is far more stable. In general, the more variable the effects, the larger the sample you will need. Physics and Chemistry usually deal with very stable effects, so they need a small sample. Psychology, Sociology and other Social Sciences usually deal with very variable effects, so they need LOTS of people to be sure the effects they see are real. In general, the larger the sample is, the more accurate our results are. Large samples also ensure a normal distribution and other advantages for statistical testing, but these samples must be RANDOM samples or they do not mean what we think they do.
it means the data is different; the data varies.
The dependent variable varies due to effects of the factor being tested in a controlled experiment.
Independent Variables are the factors that are tested by beingvaried by the experimenter.
In a controlled experiment, the one factor that differs is the independent variable. This is the variable that is deliberately changed or manipulated by the researcher in order to observe its effect on the dependent variable. The goal of a controlled experiment is to isolate the impact of the independent variable on the dependent variable while holding all other variables constant.

That varies with battery chemistry.
Well water can contain iodine, as it can be naturally present in soil and rocks. However, the concentration of iodine in well water varies depending on geological factors and location. It's recommended to have your well water tested to determine the presence and levels of iodine.
CPU speed
It varies; it depends on such factors as what you are doing and your weight.
It varies with each given number.
Vibrations
It varies depending on factors such as the dosage and individual tolerance, but typically chloroform can induce unconsciousness within minutes and its effects can last for around 30-60 minutes. However, chloroform is a dangerous and potentially lethal substance, and its use for inducing sleep is highly discouraged due to its harmful effects on the body.
