  1. Experimental Review Example

  2. Instructions • Independent Variable – the variable being tested, the treatment (what’s being compared or changed) [YELLOW] • Dependent Variable – the effects of the variable being tested (what’s being measured) [GREEN] • Control Group – the treatment of the independent variable used to determine if there has been an affect ( the “normal” was of doing something used for comparison) [PINK] • Trials – how many times the each treatment was tested (NOT the total number of test subjects) [CIRCLE] • Conclusion – a reasonable inference about the affect of the independent variable on the dependent variable (you must use specific data to support your ideas!) [BOX] • None of these experiments are completely “fair” and each of them could possibly be improved so that the conclusion is more solid. Next to the STAR, write down one suggestion for improvement and why you think it would make the experiment or the results better.

  3. Example: Mr. Krabscreated a secret ingredient for a breath mint that he thinks will “cure” the bad breath people get from eating crabby patties at KrustyKrab. He asked 100 customers with a history of bad breath to try his new breath mint. He has 50 customers (Group A) eat a breath mint after they finished eating a crabby patty. The other 50 (Group B) also received a breath mint after they finished the sandwich, however, it was a regular mint without the secret ingredient. Customers were told which mint they were getting. Two hours after eating the crabby patties, 30 customers in Group A and 10 in Group B reported having better breath than they normal do after eating crabby patties.
