"Empirical" evidence.
If the personal opinion of a scientist affects the way that the experimental results are reported, that is called bias.
A factor that is kept the same between the control and experimental groups is called
The group which does not receive experimental treatment is the control group, the group which does receive the treatment is the experimental group.
You must have a control group, an experimental group, an experimental variable (also called the independent variable), and a response to be measured (also called the dependent variable). The experimental variable is applied only to the experimental group, so that any difference between the control group and experimental group is due only to the experimental variable. Both the control group and experimental group must have the same conditions, except for the experimental variable.
A testable explanation that is supported or refuted is called a hypothesis.
Law
In science, and most specifically chemistry, the accepted value denotes a value of a substance accepted by almost all scientists and the experimental value denotes the value of a substance's properties found in a localized lab.
ERROR is the experimental value-accepted value.
If the personal opinion of a scientist affects the way that the experimental results are reported, that is called bias.

The conclusion
Hypothesis.
It is called the control variable. It is used to compare to your experimental results.
It is called a theory because they are well supported by observations and experimental evidence.
It is called communicating and it is a great way for scientists to compare and share their results.
This would be called a well established theory.
A study that compares the results of a control group with those of an experimental group is usually referred to as a controlled experiment. This design helps researchers assess the impact of a variable of interest by holding other factors constant.
