What is the part of an experiment to which you compare the results of the other tests?

Explain the relationship between a placebo and a control group?
Let's say a medical lab is doing en experiment. They would take a control group and give a certain % of people the placebo and the rest a real drug and compare the affects it had on the patients. One argument is if people "believe" they are taking the real drug it can actually affect them physically.
What purpose is served when a test is done using water instead of a sample substance?
Distilled water is has virtually all of its impurities removed. Distillation involves boiling the water and then condensing the steam into a clean container, leaving most if not all solid contaminants behind. If you do not want the impurities in the water to affect the outcome of the test you need to use pure water.
What is chemical control?
Control with the use of chemicals
Why do you need to have a control group when conducting experiments?
The control group gives you something to compare the results to.
What is used as a way to compare values for a dependent variables in many experiments?

What is used as way to compare values for dependant variables in many experiments?
experimental control
Why is experimental control needed in experiments?
The experimental control is what you compare your experimental data with. Without the control, you can't tell if the variable you are testing is what is causing your results.
Why should expieriments have a control group?

Do all experiments need to have a control group?
yes all experiments need to have a control
What is the part of an experiment that is not being tested but used for comparisons?
Any experiment is associated with a control . This control is actually not a part of experiment itself but is only used to compare the results. for eg in DNA transformation experiments control DNA is also tranformed to analyse and compare the transformation of our required DNA insert.

The full quetion is:Why are controls not needed in the arthropods experimentA some experiments cannot have controlsB All experiments must use controlsC compare treatments to each other instead of to a controlD hypothesis is not falsifiableThe treatments in this experiment can be compared to each other instead of to a control.
Why do scientist use control groups in experiments?
Because it helps them know the results of the objects in the experiment and how they differ. This way the scientist knows which succeeded and which failed.
