WEEK $5$ ASSIGNMENT: T$-$TESTS AND ANOVA

You are a DNP$-$Prepared nurse tasked with evaluating patient care at your practice compared to patient care at affiliated practices. You have noticed that a key complaint from your patients concerns the wait times associated with each patient visit. Based on these complaints, you have decided to compare the wait times at your practice to the wait times at affiliated practices. After recording the wait times at each practice, for $50$ individual patients at each practice, you are now prepared to analyze your data. What approach will you use to analyze the data?

In the scenario provided, you might decide to use, the Analysis of Variance $($ANOVA$)$ approach. "ANOVA is a statistical procedure that compares data between two or more groups or conditions to investigate the presence of differences between those groups on some continuous dependent variable" $($Gray & Grove, $2020).$ ANOVA is often a recommended statistical technique, as it has low chance of error for determining differences between three or more groups.

For this Assignment, analyze the ANOVA statistics provided in the ANOVA Exercises SPSS Output document. Examine the results to determine the differences and reflect on how you would interpret these results.

WEEKLY RESOURCES

TO PREPARE:

Review the Week $5$ ANOVA Exercises SPSS Output provided in this week's Learning Resources.

Review the Learning Resources on how to interpret ANOVA results to determine differences.

Consider the results presented in the SPSS output and reflect on how you might interpret the results presented.

Summarize your interpretation of the ANOVA statistics provided in the Week $5$ ANOVA Exercises SPSS Output document.

Note: Interpretation of the ANOVA output should include identification of the $-$value to determine whether the differences between the group means are statistically significant.

Be sure to accurately evaluate each of the results presented $($descriptives$,$ ANOVA results, and multiple comparisons using post$-$hoc analysis$)$
