Analyzing Parametric Statistics
As a practice scholar, you are searching for evidence to translate into practice (healthcare mental illness depression). In your review of evidence, 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?
•
• Differentiate selected statistical methods for the purpose of translation science
• Evaluate selected statistical methods for the purposes of critical appraisal of evidence
• Synthesize literature relevant to practice problems.
