What is the purpose of using a control in scientific experiments?

∙ 9y ago
The experimental control provides a base-line result or set of results, from which you can compare the variables' effects against. It's designed to minimize the effects of variables (other than the single independent variable). Control groups are often included in medical or psychological experiments so that the results of an experiment are considered reliable and trustworthy.
Example:
A mystery-drug cure is being tested. One group of patients is given the drug and the other group is not. The group without the drug will be subject to all the same conditions that the other group are under, thereby seeking to eliminate any unforeseen effecting environmental factors. This makes it possible to compare, and therefore measure, the impact any drug would have.

How are most scientific hypothesis tested?
Most scientific hypothesis are tested using the scientific method by asking questions and doing experiments.
What is the purpose of using multiple control groups in an experiments?
To help you conclude that no uncontrolled factors significantly influenced your results. To help you determine that your experimental results are valid To help control for factors that aren't being tested but might affect results
What is the different shape of scientific method?
The scientific method is a scientific method for systematically acquiring new knowledge. The scientific method is typically applied to experiments, involving taking a hypothesis and using it to get applicable results.
Experiments using potentiometer and error involved in those experiments?

What is scientific bias and how do you avoid it?
There are numerous biases (e.g., knowing which subjects are assigned to which experimental groups). Most can be avoided by using proper Control procedures (e.g., using a double-blind design) and using proper control groups.
What is the purpose of using scientific method in psychological experiments?
It is used to avoid common problems that occur in the absence of using the scientific method.
How are most scientific hypothesis tested?
