∙ 15y agoYou have a test group in a controlled experiment so that you can tell what happens when you DO whatever it is as opposed to when you don't. It's to help define your findings. If that makes any sense at all...
In an experiment there are two groups: the Control, and the Test Group. The control is isolated and not exposed to the same things the test group is. The test group is tested upon, and in the end they use the control group (who would be unaffected 'or normal') to see the effects of the test on the test group by way of comparing.

What is part of an experiment that is not being tested an is used for comparision?
This probably refers to the 'control'. In a very simple experiment you may add food colouring to a solution to see what colour it sent the solution. You would also have a second sample of the solution which you would not add food colouring to. This would be your control and would serve the purpose of making sure that the solution wouldn't have changed colour by itself anyway. It would also be there for comparison, so that you could compare the colours to see just how much the colour had changed.

Does every experiment require a control?
A control group is an essential part of any experiment because it allows you to reach a reliable conclusion. For example, let's say that you wanted to test out a new diet pill to determine how effective it was. You would need to obtain test subjects and divide them into two groups. The first group would be given the new diet pill while the second group (your control group) would be given a placebo. If at the end of the designated time, the first group lost more weight (a statistically significant amount more) than the control group, you would be able to state conclusively that the pill was effective for weight loss. In the absence of a control group, it would be unclear whether the cause of the weight loss in your subjects was due to the diet pill or other unrelated factors.

Why is it wrong for a researcher to assign the first subjects to show up for an experiment to the experimental group and the second group of subjects to arrive to the control group?
Assigning subjects based on arrival time can introduce bias into the study, as there could be systematic differences between subjects arriving early and those arriving late. This could confound the results of the experiment and make it difficult to determine the true effect of the treatment. It is essential to randomly assign subjects to experimental and control groups to ensure the groups are comparable at the start of the study.
