- Is there a connection between caffeine and headaches? Is there an association between hospital wait times and patient care? Is there a relationship between antibiotic use and weight gain?
Correlation statistics all begin with a research question, and these research questions all seek to determine relationships between variables. Correlational analysis clarifies relationships, but there are many ways to formulate a correlation. Therefore, the strength of a correlation relies on the variables used and the interpretation of the results that may signify a statistically relevant association or relationship.
For this Assignment, you will examine how to interpret results obtained through a correlational analysis. You will evaluate the correlation results provided in the Week 6 Correlations Exercises SPSS output and will reflect on the meaning of the results for the variables examined.
To Prepare:
- Review the Week 6 Correlations Exercises SPSS Output provided in this week’s Learning Resources.
- Review the Learning Resources on how to interpret correlation results to determine the relationship between variables.
- Consider the results presented in the SPSS output and reflect on how you might interpret the results presented.
The Assignment: (2–3 pages)
Answer the following questions using the Week 6 Correlations Exercises SPSS Output provided in this week’s Learning Resources.
- What is the strongest correlation in the matrix? (Provide the correlation value and the names of variables)
- What is the weakest correlation in the matrix? (Provide the correlation value and the names of variables)
- How many original correlations are present on the matrix?
- What does the entry of 1.00 indicate on the diagonal of the matrix?
- Indicate the strength and direction of the relationship between body mass index (BMI) and physical health component subscale.
- Which variable is most strongly correlated with BMI? What is the correlational coefficient? What is the sample size for this relationship?
- What is the mean and standard deviation for BMI and doctor visits?
- What is the mean and standard deviation for weight and BMI?
- Describe the strength and direction of the relationship between weight and BMI.
- Describe the scatterplot. What information does it provide to a researcher?
