Essential Information. Professionals in hospital management, also known as health services management, usually have the job title of hospital manager or hospital administrator. They typically coordinate and direct the delivery of healthcare services in a hospital system.
Student's t-test. A t-test is any statistical hypothesis test in which the test statistic follows a Student's t-distribution under the null hypothesis. It can be used to determine if two sets of data are significantly different from each other.
If not the t-test, then what? If the t-test is not appropriate, then one alternative is a nonparametric test, such as Wilcoxonâs test. Another alternative is a permutation test, or a bootstrap. In my opinion, all three alternatives ought to be used more often. Suppose one wishes to test if men are heavier than women in a given population.
