Analyzing Parametric Statistics

You locate a quasi-experimental research study as possible evidence to support a practice change. You notice that the study aims to make a prediction that relates to correlation between study variables. The study sample size is large and normally distributed. Reflect upon this scenario to address the following.

· In your appraisal of the evidence, you note that an independent variable is not present and that a Spearman’s ranked correlation is used to analyze data. Is this the correct level of correlational analysis? Explain your rationale.

· Are association and correlational analysis equivalent in determining relationships between variables?

· Do these findings impact your decision about whether to use this evidence to inform practice change? Why or why not?
