Detailed explanation-1: -Negative control group: In this type of control group, the participants are not given a treatment. The experimental group can then be compared to the group that did not experience any change or results. Placebo control group: This type of control group receives a placebo treatment that they believe will have an effect.
Detailed explanation-2: -An experimental group is the group that receives the variable being tested in an experiment. The control group is the group in an experiment that does not receive the variable you are testing. For your experiment, the bag of popcorn that remained stored in the cabinet is the control group.
Detailed explanation-3: -In experimental research, the control group is the group of participants that do not receive the experimental treatment and serves as the standard for comparison.
