Assignment
Based on your proposed topic and construct(s) or variable(s) of interest, write a Research Question and Hypotheses (null and alternate) that reflect the need to conduct a Pearson correlation coefficient statistic in order to test the hypotheses. Include detailed information regarding Pearson correlation coefficient applications and data results.
My chosen topic is:
“Exploring The Care
and Management of Patients with Ehlers Danlos Syndrome and the Physician
Perception”
I have attached the last essay for reference. (I did not receive maximum points, so there were some things that could have been improved).

CORRELATION STATISTICS
Inferential statistical analysis always occurs after Descriptive statistical analysis. The most common inferential statistical analysis involves correlation (i.e., a relationship between 2 variables/constructs of interest). While there may be more than 2 variables of interest, correlation coefficient statistics can only be applied to 2 variables at a time. For example, the most common correlation is that between height and weight. We would assume as height increases, so does weight. That would be representative of a positive correlation hypothesis. With data from a sample of interest, we could test if indeed weight increases with height increases, or not. If you add another variable into the mix like age, we actually have 3 combinations of correlations (ABC = A-B, A-C, B-C) that are possible:
Age and Height
Age and Weight
Height and Weight
