• Competency 1: Describe underlying concepts and reasoning related to the collection and evaluation of quantitative data in health care research.
o Interpret the overall clinical meaning and limitations of the relationship of two variables, based on a correlation analysis and literature regarding age and stress.
• Competency 2:Apply appropriate statistical methods using common software tools in the collection and evaluation of health care data.
o Create a histogram and scatter plot for variables tested for normal distribution.
o Perform a normal distribution assumption test for two variables to determine if data is normally distributed.
o Perform an appropriate correlation test to determine the direction and strength or magnitude of the relationship between two variables.
• Competency 3:Interpret the results and practical significance of statistical health care data analyses.
o Interpret the effect size for correlation analysis results.
• Competency 5: Address assignment purpose in a well-organized text, incorporating appropriate evidence and tone in grammatically sound sentences.
o Articulate meaning relevant to the main topic, scope, and purpose of the prompt.
o Apply APA formatting to in-text citations and references.
Instructions
For this three-part assignment, complete the following, referring to the helpful links in Resources:
Part 1: Graphic Representation of the Data From the Yoga Stress (PSS) Study Data Set
1. Using the readings, media, and resources discussed to date, create a histogram or bar graph (according to the measurement level of the data) of the following variables: Age, Education, Pre-intervention Psychological Stress Score (PSS). Done
2. Using the readings, media, and other resources discussed to date, create a scatter plot of the following pair of variables: Age Versus Pre-intervention Psychological Stress Score (PSS). Done
Part 2: Statistical Tests
1. Perform a pre-analysis assumption test for a normal-distribution test to determine if the data you intend to use for the correlation tests passes the assumption of being normally distributed. Done
o You will use this test for Age and Pre-intervention Psychological Stress Score (PSS).
2. Perform the appropriate correlation test to determine the direction and strength or magnitude of the relationship between these two variables from Step 1.
o Remember, we are not concerned about causation at this point and want to determine only if there is a statistical association.
Part 3: Yoga Stress (PSS) Study Paper
• Include the histogram and scatter plot graphics you created earlier for Age and Pre-intervention Psychological Stress Score (PSS).
o Provide an interpretation for these graphics.
• Report the statistical outcome of the correlation analysis using appropriate scholarly style, including a brief interpretation of the effect size of the correlation.
• Interpret the practical, real-world meaning (and limitations of the interpretation) of the relationship of these two variables, based on the correlation analysis you performed.
• Include the SPSS “.sav”output file that shows your programming and results from Parts 1 and 2 for this assignment.
• Provide at least one evidence-based scholarly or peer-reviewed article that supports your interpretation.
Additional Requirements
