Statistical Assessment

Use the chart in the Module 4 lecture to complete the table below to assess the appropriateness of the statistics used, and determine the statistical significance of outcomes in Messina’s, et al., article “The Relationship Between Patient Satisfaction and Inpatient Admissions Across Teaching and Nonteaching Hospitals” . Refer specifically to the discussion on pages 189-90 of the article.

Statistical Significance:

There were three errors in Table 4 on page 185. In your identification of significant findings, can/did you find them?

The chart from the Module 4 Readings:

Statistic	Data Type	Sample Size	Research Question
Mean and Standard Deviation	Interval or ratio	>2	What does the data set look like?
Frequency Distribution	Nominal-Ratio	>2	What does the data set look like?
Chi-Square	Nominal-Ordinal	>4	Is the variance of one variable equal to or different from another variable
Correlation Coefficient	Interval-Ratio	>4	What is the relationship between two variables?
t-Test	Interval-Ratio	<30	Is there a significant difference between two groups? May be intrinsic or may be experimental
ANOVA (Analysis of Variance)	Interval-Ratio	>30	Is there a significant difference between 2 or more groups?
Regression Analysis	Interval-Ratio	>30	How much of the change in the dependent variable is predicted by the independent variable or variables?

Refer to the Module 4 Readings for explanation of the chart.
