This paper applies inferential statistical techniques — specifically t-tests and ANOVA — to evaluate patient satisfaction across three groups defined by housing problems: no housing problems, one housing problem, and two or more housing problems. Drawing on a sample of 50 patients collected at affiliated practices, the study uses Levene's test to verify variance assumptions before conducting a one-way ANOVA. Results reveal a statistically significant difference in overall satisfaction across the three groups (F(2,934) = 61.67, p < 0.05), with patients reporting no housing problems recording the highest mean satisfaction score (M = 12.71). Post-hoc comparisons identify which specific group pairings drive the overall difference. The paper concludes by calling for further investigation into the factors contributing to these satisfaction disparities.
The paper demonstrates the sequential verification approach required before interpreting ANOVA results: the author first establishes that group variances are equal using Levene's test (p > 0.05), then proceeds to interpret the F-statistic, and finally uses post-hoc testing to identify specific between-group differences. This step-by-step reporting of statistical assumptions is a core technique in quantitative health research writing.
The paper opens with a brief introduction explaining the clinical rationale and study design, followed by a summary section that integrates descriptive statistics, assumption testing, ANOVA results, and post-hoc findings in a logical sequence. A short conclusion synthesizes the key finding and proposes future research. The structure is compact and appropriate for an applied statistics assignment at the graduate nursing level.
This paper applies inferential statistical techniques — specifically the t-test and ANOVA (Analysis of Variance) — to make inferences about a sample population. In basic terms, inferential statistics aim to draw conclusions about a population using a drawn sample (Connelly, 2021). As a DNP-prepared nurse, the task involves evaluating patient care and comparing it with care at affiliated practices. Key complaints from patients regarding wait times prompted a comparison of wait times across affiliated practices. A sample of 50 individual patients was collected and analyzed using t-tests and ANOVA, which compare data between two or more groups or conditions to investigate whether differences exist on a continuous dependent variable (Gray & Grove, 2020). The ANOVA test specifically investigates differences in the mean overall satisfaction scores among three groups defined by housing problems.
The study aimed to describe and summarize the data using descriptive statistics before proceeding to inferential analysis. The primary goal was to assess differences in overall satisfaction among three groups: no housing problems, one housing problem, and two or more housing problems. Descriptive results show that the no-housing-problem group had a mean and standard deviation of M = 12.71, SD = 2.35; the one-housing-problem group had M = 11.97, SD = 2.59; and the two-or-more-housing-problems group had M = 10.57, SD = 2.59. These results indicate that patients reporting no housing problems had a higher mean satisfaction score than those in the other two groups.
Before conducting the statistical analysis, it is imperative to assess the assumptions of the ANOVA test using Levene's test for equality of variances (Nick, 2007). The results of Levene's test indicated that the assumption of equal variance was met, meaning that variance across the three groups was not significantly different (p > 0.05). This confirmed that proceeding with a standard one-way ANOVA was appropriate.
