Detailed explanation-1: -Frequently asked questions about control groups. What is the difference between a control group and an experimental group? An experimental group, also known as a treatment group, receives the treatment whose effect researchers wish to study, whereas a control group does not. They should be identical in all other ways.
Detailed explanation-2: -Statistical significance refers to the claim that a result from data generated by testing or experimentation is likely to be attributable to a specific cause. A high degree of statistical significance indicates that an observed relationship is unlikely to be due to chance.
Detailed explanation-3: -05 level of significance and the result shows that the difference is statistically significant, we can conclude that there is only a 5% chance that the observed difference between the two groups is random or due to chance.
Detailed explanation-4: -The control group is just as important as the experimental group; without it there would be no experiment. Without a control group it is impossible to confidently determine which changes or outcomes are due to the intervention as opposed to being due to some other variable.
