a control
a control
A sample that goes through all the steps of an experiment but does not contain the variable being tested is called a control group. The control group serves as a baseline to compare the effects of the variable in the experimental group, helping to isolate the impact of the variable being tested. This comparison is essential for validating the results of the experiment.
The control, or control group, goes through all the steps of an experiment, but does not contain the factor being tested, which is called the experimental variable or independent variable.
The sample size determines the accuracy of results in an experiment

An experimental sample is an experiment that is just a sample of what you are looking for.
A control sample is the experiment under regular conditions. An experimental sample is the experiment in which different variables are changed.
The sample size has no effect on the validity of an experiment: instead, it is the experimental procedure and integrity of the experimenters.The sample size can affect conclusions that may be drawn from an experiment. The larger the sample is, the more reliable these conclusions are.
It is the set of all possible outcomes of the experiment.

The negative control in the lactose experiment would be a sample that does not contain lactose or the enzyme needed to break down lactose. This control is used to show what would happen if no lactose were present for the enzyme to act on.
Statistically the larger the sample size the more significant the results of the experiment are. Chance variation is ruled out.
