What Is the Level of Treatment in a Scientific Experiment?
When you are completing a science experiment, there is usually a variable involved that you control. This is called an independent variable. If you are being asked what the level of treatment is, you can come up with the answer to this question by thinking about how the independent variable in the experiment has been varied or changed.
Level of Treatment Example
Say a pharmaceutical company is making a new drug, and it wants to test different strengths to discover which one of its three pills is most effective. The company may go about this experiment by finding 15 people who agree to test the drug. The company would then break the total population into three equal sets. One set would be given a 10 mg pill, the second set would be given a 30 mg pill, and the third set would be given a 60 mg pill. In this fictional scenario, each drug strength is considered a level of treatment.
