Drugs are often used for reducing the blood pressure of hypertensive patients (those with high blood pressure). An experiment was run to investigate the effect of Drug (A or B) and Dose Level (Low or High) on the reduction in blood pressure. The experiment was conducted separately for the 36 patients who had mild hypertension and the 24 patients who had severe hypertension as the researcher suspected that results may differ for the two groups. For this design, there are:

Patients with high blood pressure were randomly allocated to receive one of two treatments. All patients had been treated with cognitive behaviour therapy (CBT) and were then assigned (at random) to recieve no further treatment (NFT) or beta-blockers (BB). Six weeks later it was noted whether or not each of the patients showed a decrease in their blood pressure. For the NFT group 15 out of 50 patients showed a decrease after 6 weeks, whereas this happened for 26 out...
