What’s the control in an experiment?

Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.

A positive control group is a control group that is not exposed to the experimental treatment but that is exposed to some other treatment that is known to produce the expected effect. For example, imagine that you wanted to know if some lettuce carried bacteria.

What makes a good control group?

A positive scientific control group is a control group that is expected to have a positive result. By using a treatment that is already known to produce an effect, the researcher can compare the test results with the (positive) control and see whether the results can match the effect of the treatment known to work..
