Week Six – Correlations Exercises Correlations are used to describe the strength and direction of a relationship between two variables. A correlation between two variables is known as a bivariate correlation. In this module the Pearson Product-Moment Correlation will be used when running a correlation matrix. The Pearson correlation coefficient ranges from a value of -1.0 to 1.0. A correlation coefficient is never above 1.0 or below -1.0. A perfect positive correlation is 1.0 and a perfect negative correlation is -1.0. The size of the coefficient determines the strength of the relationship and the sign (i.e., + or -) determines the direction of the relationship. The closer the value is to zero the weaker the relationship and the closer the value is to 1.0 or -1.0 the stronger the relationship. A correlation coefficient of zero indicates no relationship between the variables. A scatterplot is used to depict the relationship between two variables. The general shape of the collection of points indicates whether the correlation is positive or negative. A positive relationship will have the data points group into a cluster from the lower left hand corner to the upper right hand corner of the graph. A negative relationship will be depicted by points clustering in the lower right hand corner to the upper left hand corner of the graph. When the two variables are not related the points on the scatterplot will be scattered in a random fashion. Using Polit2SetB dataset, create a correlation matrix using the following variables: Number of visits to the doctor in the past 12 months (docvisit), body mass index (bmi), Physical Health component subscale (sf12phys) and Mental Health component subscale (sf12ment). Run means and descriptives for each variable as well as the correlation matrix. Follow these steps using SPSS: 1.Click Analyze, then correlate, then bivariate. 2.Select each variable and move them into the box labeled “Variables.” 3.Be sure the Pearson and two-tailed box is checked. 4.Click on the options tab (upper right corner) and check “means and standard deviations.” The exclude cases pairwise should also be checked. Click continue. 5.Click OK To run descriptives for docvisit, bmi, sf12phys and sf12ment do the following in SPSS: 1.Click Analyze then click Descriptives Statistics, then Descriptives. 2.Click the first continuous variable you wish to obtain descriptives for (docvisit) and then click on the arrow button and move it into the Variables box. Then click bmi and then click on the arrow button and move it into the Variables box. Then click sf12phys and then click on the arrow button and move it into the Variables box. Then click sf12ment and then click on the arrow button and move it into the Variables box. 3.Click the Options button in the upper right corner. Click mean and standard deviation. 4.Click continue and then click OK. Assignment: Answer the following questions about the correlation matrix. 1.What is the strongest correlation in the matrix? (Provide correlation value and names of variables) 2.What is the weakest correlation in the matrix?

Part II Using Polit2SetB dataset, create a scatterplot using the following variables: x-axis = body mass index (bmi) and the y-axis = weight-pounds (weight). Follow these steps in SPSS: 1.Click Graphs, then click on Legacy Dialogs, then click “Scatter/Dot”. 2.Click “Simple Scatter” and then click “Define.” 3.Click on weight-pounds and move it to the Y-axis box and then click on body mass index and move it to the x-axis box. 4.Click OK. To run descriptives for bmi and weight do the following in SPSS: 5.Click Analyze then click Descriptives Statistics, then Descriptives. 6.Click the first continuous variable you wish to obtain descriptives for (body mass index) and then click on the arrow button and move it into the Variables box.

Population Health Tools – Measuring Health 2025

How Healthy is Your Community? The expression “Think Globally, Act Locally” guides your Discussion this week. By accessing information from the U.S. Department of Health and Human Services, you will have the opportunity to learn how healthy your community is. You will identify the key health issues and vulnerable populations in your own county. Understanding the factors that influence the health status of residents in your county will provide you with a local perspective to compare to global health challenges you will examine in weeks to come. To prepare for this Discussion, first learn a little about the health statistics for your county. If you are not located in the U.S., pick a state and county you might like to visit or know more about to complete this assignment. Go to the Community Health Status Indicators Report, and select your state and county to review your local report. http://wwwn.cdc.gov/CommunityHealth/homepage.aspx?j=1 Then, go to the Walden Library and find at least one recent (within last 5 years) article in addition to your Learning Resources to document, and support, the concepts you include in your Discussion post. For suggestions to help with your search, visit the Library http://library.waldenu.edu/908.htm By Day 4, post a comprehensive response to the following: Using the information available on the Community Health Status Indicators Report, provide a summary of the following information in your county. Use the article(s) you located, as well as your Learning Resources, to support your answers to the following questions in your post: 1. Identify your county and state. 2. How healthy is your county? What evidence did you use to come to your conclusion? 3. What vulnerable populations are identified in your county? Are there groups of individuals who have health disparities? Are there issues related to access to care within your county? If so, what are they? 4. Highlight the risk factors for premature death and environmental health concerns seen in you county. 5. Where does your county excel or fall behind in preventive health? Provide examples.
