Statistical significance of outcomes presented in Messina et al. article The Relationship Between Patient Satisfaction and Inpatient Admissions Across Teaching and Nonteaching Hospitals”-assess the appropriateness of the stats used Statistic types: man and standard deviation, frequency distribution, chi-square, correlation coefficient, t-Test, ANOVA, Regression Analysis/ Data type/ Sample Size/ What does the data set look like for mean & std deviation and the frequency distribution? Is the variance of one variable equal to or different from another variable (chi-square)? What is the relationship between the 2 variables(correlation coefficient)? Is there a significant difference between the two groups (t-Test)? May be intrinsic or may by experimental. Is there a significant difference between 2 or more groups (ANOVA)?  How much of the change in the dependent variable is predicted by the independent variable or variables (Regression Analysis)?
