Quantitative Data Collection and Analysis
Quantitative Data Collection and Analysis
Data can be qualitative or quantitative. Qualitative data are helpful to generate a hypothesis and gather information if little is known about an expected association. Focus groups, key informant interviews, and case studies are types of qualitative data collection methods used to identify common themes from which to build a hypothesis. Quantitative data collection and analysis are used to test a hypothesis and make comparisons to determine the direction and strength of a potential association. The Behavioral Risk Factor Surveillance System (BRFSS) is cross-sectional panel survey used to collect quantitative data on adult behaviors and risk factors. It is one of the largest U.S. health data collection efforts. The data can be used to analyze associations on a state or country level.

1.0 or
(≈ 1.0)
Means that the odds of exposure among cases is the same the odds of exposure among controls The exposure is
not associated
with the disease
> 1.0 Means that the odds of exposure among cases is greater than the odds of exposure among controls and positively associated with the outcome The exposure may be
a risk factor
for the disease.
< 1.0 Means that the odds of exposure among cases is lower than the odds of exposure among controls and negatively associated with the outcome The exposure may be
protective
against the disease.

Calculating Odds Ratio
Odds ratio is a measure of association used in epidemiological studies to assess the relationship between disease and exposure. In this exercise, you will calculate and interpret odds ratio using real-world examples.
Odds Ratio
In case control studies the odds ratio (OR) is the measure of the association between the frequency of an exposure and the frequency of an outcome. The OR is an indirect measure of risk in case control studies because incidence rates cannot be calculated.
The formula for odds ratio is: (A/C) ÷ (B/D) or (AD)/(BC).
Remember, data from an output source may not be ordered according to the table. Ensure that the output data corresponds to the table, or you will calculate incorrectly when you apply the formula.
Disease Status Exposure Status Yes No Total Yes A B A + B No C D C + D Total A+C B+D A+B+C+D For this assignment:
1. Retrieve the “BRFSS Web-Enabled Analysis Tool” resource provided in the study materials.

0. Select “2015” for the year.
0. Select “Arizona” for the state.
0. Select “Alcohol Consumption: Binge drinkers (males having five or more drinks on one occasion, females having four or more drinks on one occasion)” for Step 2 Select Row.
0. Select “Chronic Health Conditions: Ever diagnosed with a depressive disorder, including depression, major depression, dysthymia, or minor depression” for Step 3 Select Column.

0. Select “Sample Size” for Step 6 Select Statistics and run the report for the cross tabulation.
Part 1
Using the data from the cross-tabulation results, calculate the odds ratio for depression among those exposed to binge drinking. Refer to the formula provided above. Quantitative Data Collection and Analysis
