Objective: To evaluate Trident's claim that "Chewing Trident after eating cleans and protects teeth."

Background: Bubblicious is suing Trident over false advertising, claiming that the false advertising has harmed their profits. The courts have hired you as a researcher to determine the veracity of Trident's claim. Both Trident and Bubblicious have hired their own researchers, who will have access to your plans and results to ensure their validity.

Design Challenge: Design a study that controls for all threats to internal validity and evaluates Trident's claim. Be sure to consider possible confounds and how to control them. The courts have provided you with $100,000 in funding, payable by the losing client.

Report:

1) Introduction

a) Summary of 1 supporting peer-reviewed journal article

b) Current study with hypothesis about which gum will perform best.

2) Method

a) Participants – make up the participants you want and describe how many, their age range, their gender and race breakdown, etc.

b) Materials – make up the materials you want to use; these must include at minimum Trident gum and a way of assessing the effects of Trident gum (i.e., a method that checks dental variables).

c) Procedures – make up how participants would go through your study, which groups you will use, when and how participants will chew gum and have their dental variables assessed, etc.

3) Results: Describe the analysis you would perform on your data (i.e., state the statistic and what groups you would compare).

4) Discussion

a) Describe how your methods control for all nine threats to internal validity.

i) History

ii) Maturation

iii) Testing

iv) Instrumentation

v) Regression to the mean

vi) Selection

vii) Attrition

viii) Diffusion of treatment

ix) Sequence effects

b) If you failed to control for confounds, change your study to control them.
