MODULE 3 ACTIVITY Correlation and Regression Purpose: The purpose of this learning activity is to demonstrate the understanding of correlation and regression and how they could be important in your future practice. Instructions: Submit 1 paragraph answering the following questions: What are the differences between results that demonstrate a correlation between two variables and results where a regression is run using two variables? Correlation and regression modeling are the most commonly used techniques for evaluating the relationship between variables. Correlation gives us a direction of common occurrence. If two variables are positively related (i.e., when one is present, the other will be present), we would say that there is a strong causal relationship between the variables. If they are negatively related (where as one factor increases the other factor decreases), then we can say they have an inverse relationship. Regression modeling allows us to create an equation that gives a line of fit that tells us just how strong the relationship is and make predictions. For simple correlations (positive or negative), we most often use something akin to a point-slope model (y=mx+b). On some occasions, such as therapeutic response to a drug, there are limits to the efficacy of the intervention – too little and there will be no effect. Conversely, too much of the intervention and the outcome is adversely affected. Therefore, dose-dependent responses can sometimes be modeled using a parabolic line of fit. Think about your future clinical role and provide a clinical example of variables that you may want a correlation analysis run and explain. In much of Primary Care, the goal is harm reduction and mitigation of modifiable risk factors that are linked to disease. We already know a great many of these risk factors, but the global COVID-19 pandemic has introduced a new set of variables which will bear close monitoring for adverse outcomes. It is overly simple to merely exam the incidence of – say – pulmonary fibrotic disease or CHF in the population who contracted COVID. Nurses pay attention to social determinants of health. The isolation and economic hardships brought on by the pandemic – as well as educational and developmental setbacks that school age children experienced. Think about your future clinical role and provide a clinical example of variables that you may want a regression analysis run and explain. As mentioned above, I think that COVID provides a target rich environment for exploration. A nursing project that has been rolling around in my mind is whether or not progression to or of Chris Larimer Biostatistics 107 2024-03/24
dementia was hastened by the adoption of widespread masking. We already have seen some of the educational and developmental difficulties children faced when unable to read emotions behind masks or follow lips in order to better understand phonemic associations. I would like to study rapidity of dementia onset and worsening in the setting of facial masking. Within the states, we have examples of forced vs. voluntary compliance. We also have a population in Japan and the Far East who have historically had high levels of masking prior to the pandemic. If there is a significant difference between American vs. Asian populations, and differences between forced vs voluntary mask use, it may guide our future responses to similar public health crises.
