Choosing the Design of an Experiment
Complete each part of the questions. Since the goal of many of these questions is to specify the details of a proposed experimental design, your descriptions must be clear and specific.
1. The Academy of Sports Medicine Physicians is interested in determining whether a new training regimen will help long distance runners improve their performance in marathons. This organization comes to you for some advice on how to design an experiment to test whether this new regimen is more effective than the standard regimen. You have access to a sample of long distance runners on the track teams at ten different universities. You hope to conduct the experiment over the course of two years because the regimen takes a long time to learn and because you want to include new runners in the sample as they join the track team. You also believe that the effect of the regimen on performance may differ for men and women.Your challenge is to design an experiment that uses a randomized approach tomeasure the effect of the new regimen on performance.
Remember, your design should take into account your concerns about different effects for men and women and should be set up so that new subjects can be properly includedin the experiment. Create an experiment that will address these concerns. Pay particular attention to the factors, explanatory and response variables, anyblocks or matching characteristics, and the treatment conditions used in the experiment.
As much as possible, use diagrams instead of words to summarize your experimental design.
Explanation / Answer
I will try to design the experiment, we must consider
1-Replication, the experiment can be repeated on different conditions and on different groups,
2- Control, this is accounting for all othe potentially influential variables. This can be accomplished by radomization,
for example subjects can be radomly assigned to a control group that does not follow the new training regimen.
3-Radomization, this is the pactice of radomly assigning experimental units to training and control groups.
I think, we can take (for example) 1,000 runners and radomly give 500 runners the new training and then compare the perfomance of the two groups.
