Would this experiment require a control group?

Would this experiment require a control group?





hi im doing an experiment- whether a species of beetles are attracted to a specific color...the experimental group would be exposed to different colors at different times. would this experiment require a control group...if so what would it be? Thankyou!|||it seems to me that this would require a control group


a control group would give you a baseline to measure the experimental group against


if the exp. group responds in the same way as the controls then the colors have no effect


but if there is a difference, then the dependent variable can be measured against the controls
