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.

For this assignment, use the “BRFSS Web-Enabled Analysis Tool” and the “Calculation Odds Ratio” worksheet. Refer to the “Odds Ratio Interpretation” document for assistance as needed.

You are required to cite to a minimum of two sources to complete this assignment. Sources must be published within the last 5 years and appropriate for the assignment criteria and public health content.

While APA style is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines, which can be found in the APA Style Guide, located in the Student Success Center.

I need this by Tuesday, (2-23-2021). I have attached 2 attachments reguired for this assignment as well as the rubric.

Odds Ratio Interpretation

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.

For this assignment:

1. Retrieve the “BRFSS Web-Enabled Analysis Tool” resource provided in the study materials.

0. Select “Cross Tabulation.”

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. Skip Steps 4 and 5.

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.
