a group of doctors used a t test to compare cancer patients’ recovery rates during the time spent in hospitals with the time spent in their own home to decide the best place for patients to be during recovery. their study measured all the patients’ white blood cell counts while they were in the hospital and then again while all patients were at home. what type of design is this?

Respuesta :

The type of design is within-groups.

A t-test is a statistical test that compares two samples' means. It is used in hypothesis testing with a null hypothesis that the difference in group means is zero and an alternate hypothesis that the difference is not zero.

When the population standard deviation is unknown, the Student's t-test is used to test hypotheses about the mean of a small sample drawn from a normally distributed population.

The Student's t test compares means between two groups, whereas ANOVA compares means between three or more groups.

In ANOVA, the first step is to obtain a common P value.

A significant P value of the ANOVA test indicates that the mean difference between at least one pair was statistically significant.
