Post  pallav on Fri Mar 30, 2012 6:16 pm

Blood Pressure 2: Problem


Suppose that a pharmaceutical company has recently focused on the effect of its potential products on blood pressure. Researchers conducted a study in which the subjects were 72 individuals with one of three diseases. Eighteen individuals were randomly assigned to each of the four drugs. The treatments were administered over time and the increase in systolic blood pressure was recorded.

QUESTION
Perform a one-way ANOVA to determine whether there are significant differences between the mean increases in systolic blood pressure for the four drugs. If there are, you need to determine which drugs differ and how greatly they differ?????


The Drug data set contains data from an experiment to evaluate the effect of four different drugs on blood pressure for individuals with one of three possible diseases.

Name Type Description
Drug char drug (1, 2, 3, 4)
Disease char disease (A, B, C)
BPChange char change in systolic blood pressure
