Question

a large study used records from canada's national health care system to compare the effectiveness of two ways to treat prostate disease. The two treatments are traditional surgery and a new method that does not require surgery. The records described many patients whose doctors had chosen each method. The study found that patients treated by the new method were significantly more likely to die within 8 years. You have 300 prostate patients who are willing to serve as subjects in an experiment to compare the two methods. Describe a completely randomized design for this experiment. Write a few sentences describing how you would implement your design.

Answer 1

Answer:

• compile the list of the 300 prostate patients considering various diversities  i.e. various ages, various stages of the disease, various racial, social and economic background , various lifestyles as well.
• divide the sample into two groups, ensuring that each group is diversified equally
• Assign each group to the one of the two treatment procedures
• follow up on the different group after treatment
• compare the measurable variables from both groups after treatment in order to determine which treatment method is best

Step-by-step explanation:

A completely randomized design for this experiment can be carried out following the following steps

• compile the list of the 300 prostate patients considering various diversities  i.e. various ages, various stages of the disease, various racial, social and economic background , various lifestyles as well.
• divide the sample into two groups, ensuring that each group is diversified equally
• Assign each group to the one of the two treatment procedures
• follow up on the different group after treatment
