Experimental Variables

In order to have a successful, reliable experiment you need sufficient data and evidence, reliable research, variables to test and a follow – up experiment. There are several types of variables you need to do an experiment. An independent variable is the manipulated experimental factor that is changed to see what the effects are. A dependent variable is the outcome. This factor can change in an experiment in reaction to the changes in the independent variable. An experimental group is the group of participants that are exposed to the change that the independent variable represents. The control group is participants who are treated in the same way as the experimental group except for the manipulated factor which is the independent variable (King 24). Proper data, evidence and research is also needed so the experiment turns out correctly and you know what you are testing. A follow – up experiment is not required, however it helps the validity of the conclusion of the experiment. Validity is “the soundness of the conclusions that a researcher draws from an experiment” (King 25). Conducting a follow – up experiment will help researchers and people alike see if the experiment worked properly, continues to help people and see how participants are doing after the experiment is over.

In this day and age anyone can write anything and put it on the internet for everyone to read. You have to be diligent in separating fact from fiction. If you are skeptical you may have to do your own research to see where the information originated. Do not believe everything you read just because it states it was from a study as it may not be reliable or truthful. Both of these studies had interesting information, however since they both were lacking sufficient data it was hard to determine if the studies were completely honest and adequate or not.
