- Find an article or webpage (do not use Wikipedia or an AI source) that lists the assumptions for correlations. Find information from the Eskandari Kootahi et al. study and determine if they were met in this study. This can count as the article related to a statistical concept this week
- You used the term “homoscedasticity.” What does this mean?
- The relationship between all of the variables was positive. What does this mean? Do both variables go up together in value? Or do both variables go down together in value? Or, as one variable goes up or down, does the other variable move in the opposite direction? Determine the direction of the effect of one of the subscales of professional values on job satisfaction and explain what this means in terms of the direction of the r-value.
- Use the values in Box 9.1 to more precisely evaluate the strength of each of the correlations between job satisfaction and professional values in this study. Give the r-values and the strength of the value.
- A complete analysis of the clinical significance of research findings is not based on the importance of the variables. Clinical significance is based on four things:
- The strength of the relationship or difference between and among the variables.
- Your knowledge of the importance of the professional issues relevant to the variables (as in this study) or the physiological or psychological impact of an intervention on the dependent (outcome) variable (in a clinical study of the effect of an intervention on the health of patients).
- Critical thinking related to the importance of the issue and the strength of the findings from the study.
- Your knowledge of your setting and your patients/staff members related to the relevance and strength of the findings to your setting and patients/staff. This should include consideration of the cost and effort of instituting and maintaining a project that aims to make a change in practice or process in your setting.
- Using the four criteria above related to clinical significance and thinking of your setting and previous practice change projects in your setting, is the strength of the correlations in this study sufficiently large to justify the effort, time, and expense of implementing a project?
