Week 2 Assignment

Descriptive Statistics in Excel

Surveys are often used to gather public health information or data. The first step in analyzing the survey data is to conduct descriptive statistics. Descriptive statistics help provide basic information about the sample group, such as the average age and average income. This information can then be analyzed to effectively measure and describe a population’s health status, behavior, and associated risk factors in relation to these variables.

The purpose of this assignment is to use Excel to apply descriptive statistics in order to describe the sample who completed a health behavior survey. Use the “Health Behavior Data Set” and the “Descriptive Statistics in Excel Worksheet” to complete this assignment. Refer to the instructional videos in the topic Resources as a guide.

For this assignment:

Use the “Data Analysis ToolPak” add-in and Pivot Tables to complete this assignment. Refer to the “Data Analysis ToolPak” resource, located in the topic Resources. Click on the link and select either Windows or Mac for instructions. The Microsoft Excel add-in will enable you to conduct descriptive statistics in Excel.

Read the “Health Behavior Case History and Survey” document to familiarize yourself with the survey and its purpose. You do not need to complete or submit the survey. It is for informational purposes only.

Open the “Health Behavior Data Set” in the Excel. Analyze the survey data and answer the questions in the “Descriptive Statistics in Excel Worksheet.”

Submit the “Descriptive Statistics in Excel Worksheet” to the assignment dropbox.

APA style is not required, but solid academic writing is expected.

Week 4 Assignment

Application of the Pearson Correlation and Chi-Square Test

The chi-square test of independence is used to determine whether two or more samples of cases differ on a nominal level variable. A Pearson correlation is used to determine the relationship between two continuous variables. Both the chi-square test of independence and correlation are widely used in the analysis of public health data.

The purpose of this assignment is to practice calculating and interpreting the Pearson correlation coefficient and a chi-square test of independence. After analyzing the data, communicate the results of one of the tests in a PowerPoint presentation. Refer to the Using and Interpreting Statistics: A Practical Text for the Behavioral, Social, and Health Sciences textbook and instructional videos for assistance completing this assignment.

Part 1

Use SPSS “Health Behavior Data Set” and complete the following:

Conduct a Pearson correlation to determine the relationship between age and annual income.

Conduct a chi-square test to determine the relationship between sex and smoking status.

Week 8  Assignment

Benchmark – Analyzing and Reporting Data

Complete this assignment according to the directions provided below.

Overview

The use of quantitative and qualitative data in a single study is referred to as a mixed methods approach. The quantitative survey data help to identify health-related trends and patterns within the sample group. Qualitative data complement the quantitative element and help to determine why and how a phenomenon exists. The cumulative findings can then help public health professionals form a conclusion about the health issue and inform future public health research, policy, and practice. The content that you create for this assignment is similar to the steps you would take as a public health professional to create and disseminate a manuscript for publication.

In this assignment, you will conduct a retrospective analysis of the publicly available Titanic Datasets. The purpose of this assignment is to analyze qualitative and quantitative data to answer the following research question: What were the causes/mechanisms that led individuals on the Titanic to survive or perish? Examples of explanatory variables that may lead to higher probability of surviving on the Titanic are class, gender, physical strength, social ties, cabin location, etc.

Please note there is inherent bias in those who provided a testimony, because it only includes those that survived.

Background Information

The Titanic hit an iceberg on April 14, 1912, at 11:40 p.m. and sunk completely about 2 hours and 40 minutes later.

A total of 2207 individuals were on board at the time of the collision and only 710 survived, despite the fact that the lifeboats could have saved 1178, so they had been used at only 60% of their capacity.

The survival rates of individuals differed greatly according sex, classes, and types of crew.

For this assignment, you will use:

The quantitative Titanic dataset.

Qualitative testimonials from either Boat 1, 6, or 16.

Note: You will conduct the analyses for Parts 1 and 2. You will then use this information to write Part 3: Mixed Methods Paper

Part 1: Quantitative Analysis

Review the “Quantitative Titanic Dataset” and the accompanying “Codebook.” Consider what descriptive and inferential statistics you will conduct to help answer the research question.

Prepare the data to complete the analysis.

Using SPSS, conduct descriptive statistics to summarize the sample.

Using SPSS, select appropriate quantitative inferential statistical tests to analyze the data to answer the research question.

Part 2: Qualitative Analysis:

Select testimonials from one boat to review by using the Boat 1, Boat 6, or Boat 16 zip files.

Based on your findings in Part 1 (Quantitative Analysis), read and review testimonials from the boat. Code the transcripts and identify at least three key themes.

Part 3: Mixed Methods Paper

Prepare a 1,250-1,500-word paper to address the following. Headers should be used based on the component structure outlined below:

Introduction

Discuss the relationship between socioeconomic status and health from a general perspective.

Summarize the purpose of this research study and the proposed research question.

Explain what implications this has on future public health policy and programs.

Discuss the overall study limitations.

General Requirements

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

Prepare this assignment according to the guidelines found in the APA Style Guide, located in the Student Success Center.
