This assignment will help you understand how to develop a research study. In order to do so, you must identify your research question, your independent variable and dependent variable, and your control and experimental groups. In this case you are designing a study to determine if BEST brand toothpaste is the “best” toothpaste. In order to conduct an experiment you have to control for variables that may influence your outcome. In this case, it could be diet, frequence and length of brushing, flossing or not, using mouthwash, or not. etc. You also should consider the age of the subjects, dental history, etc.
Assignment Instructions
Much of the concepts discussed in this assignment are in chapter 1 of your textbook. This assignment requires that you identify the independent variable, the dependent variable and to design an experiment in which you are comparing the brand BEST toothpaste with another brand of toothpaste. The first thing is to state your hypothesis. In this case your hypothesis would be:”Using BEST Toothpaste will reduce your number of cavities” Your IV would be the brand of toothpaste and your DV would be the number of cavities. You will have to determine who would be in the control group (the group of subjects not using BEST toothpaste), the experimental group (the subjects using BEST toothpaste).
Your job is to determine who your subjects are ex. males or females, their ages, how you control for factors that might influence the outcome of your study. What they eat, what they drink, how often they brush their teeth, whether they floss or not, use mouthwash, etc.
You can provide your answer in outline form or paragraph form.
