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
