Statistical Assessment

Write a paper of 1,000-1,250 words regarding the statistical significance of outcomes as presented in the
Messina et al. article, “The Relationship Between Patient Satisfaction and Inpatient Admissions Across
Teaching and Nonteaching Hospitals.”
Assess the appropriateness of the statistics used by referring to the chart presented in Lecture 4 and the
“Statistical Assessment” resource.
Discuss the value of statistical significance vs. pragmatic usefulness.
Prepare this assignment according to the guidelines found in the APA Style Guide, located in the Student
Success Center. An abstract is not required.

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.

Statistic Data type Sample Size Research Question

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?
