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.
When we have only two samples we can use the t-test to compare the means of the samples but it might become unreliable in case of more than two samples. If we only compare two means, then the t-test (independent samples) will give the same results as the ANOVA. It is used to compare the means of more than two samples.
