im having problems understanding this question can someone please explain it to me?In Biology (chemistry) what is primary reason including a control group within the design of an experiment?
To prove that your experiment works (or doesn't work).Think about it - if you have one group as the test group and one on a placebo (or whatever your experiment doesn't involve) then you'll get a clear distinction as to what your experiment achieved. Having just a test group leaves the impact of your experiment in the air.
Hope this helps.In Biology (chemistry) what is primary reason including a control group within the design of an experiment?
Control group is something that you don't do whatever you're studying on. If lets you know if what you did really did affect them or was there something you didn't know about that affected all animals that wasn't related to the parameter you changed.
You would use a control group to check the effect of something on an animal for instance. Without the control, it could be argued that any change was from some other cause.
