Answer:
b) He only has one group. He has not established a comparison
Explanation:
A randomized controlled experiment can be defined as an experiment that has two groups which it randomly assigns participants to.
These two groups are:
1.) the experimental group and
2.) The controlled group on whom the study is being performed.
Now Alberti does not have any of these groups we have listed. He performed the testing on the same people before they consumed alcohol and after they consumed alcohol. Therefore this study was not comparative in nature.
Use a body fat calculating capable scale, take measurements of the patient's height, weight, and use calculations of the circumferences of the neck, wrist, forearm, and hips.
