Constants are something that stays the same throughout the experiment. Your control group is something that u can control like amounts of something it also called the independent variable
Control in a science experiment means it stays the same and you don't do anything to it.
When some thing stays the same.
In the Science Fair, 'constants' are things that remain the same in your experiment. For example, you might want to keep the temperature constant for the duration of the experiment.
Um... try constants. ;)Constants are factors in the experiment that remain, well, constant. For example, if you have two cells in two petri dishes and you put salt in one of them, for whatever reason. Variable, the thing you change, is the salt. The constants are things like temperature, breeze, etc.
control means to take conrol in a science experiment
a control is anything that stays the same during the experiment
You will need to calculate the grand mean (x double bar) and r bar. From those values and the chart for the constants, all listed in the related link, you will be able to calculate the control limits.
Constants in the sense you mean are different to mathematical constants. They usually refer to a system in which two values are proportionate and so are of the units associated with the system.
Control in a science experiment means it stays the same and you don't do anything to it.
the basis to which you are comparing your results to
I suppose you mean physical constants such as the Heisenberg constant, the Boltzmann constant, the gas constant, the electron charge and so on. As you can see such values are independent on what kind of experiment you have, where, when and how.
it is the one thing that stays the same in an experiment
