Overview
This assignment will help you practice calculating measures of association and displaying data in an easy-to-read manner.
Scenarios
You will use the two scenarios below to complete this assignment.
Scenario 1
A study investigates the association between drinking coffee and developing heart disease. Researchers compare people with heart disease and people without heart disease to see if coffee drinkers are more likely to develop the disease. In this sample, there are 50 coffee drinkers with heart disease, 20 non-coffee drinkers with heart disease, 30 coffee drinkers without heart disease, and 100 non-coffee drinkers without heart disease.
Scenario 2
A study investigates the link between wearing a helmet while cycling and sustaining a head injury in an accident. The researchers followed 100 cyclists who always wear helmets and 100 cyclists who never wear helmets for a specific period. During the study, 5 cyclists who wore helmets and 20 cyclists who never wore helmets sustained head injuries.
Instructions
Using the scenarios above, complete the following for each scenario.
Identify the type of study design used in the scenario.
Note a reason why you think this is the correct study design.
Create a data table that displays the information in the scenario.
Calculate the appropriate measure of association for the scenario.
Show the formula that you are using for your calculation.
Interpret the results of the calculation for the scenario.
Make reference to your measure of association calculation.
Additionally, your submission will be assessed on:
Convey purpose, in an appropriate tone and style, incorporating supporting evidence and adhering to organizational, professional, and scholarly writing standards.
Submission Requirements
Length of Submission: There is no required length for your submission, but make sure you include all necessary parts for each scenario in the document that you submit.
APA Style: Use current APA style for all in-text citations, as well as the reference page (if necessary).
