Mohammed is a third year undergraduate student studying epidemiology. His professor is highly regarded in the field and Mohammed is very excited to study under him. While trying to replicate one of his professor’s experiments, Mohammed notices that another student has made a mistake while calculating the data for the experiment. In one of the equations, one of the signs is around the wrong way. This has made the results of the experiment seem really positive. However, when Mohammed does his calculations, he notices that his results aren’t very good at all. Mohammed does the calculations multiple times. He consults a few other students, and they all come up with the same thing. It isn’t an assignment, and students are allowed to collaborate and work together, so Mohammed tells the student about the mistake. However, the other student shrugs and refuses to change it because it is the same as the one used in the original paper. What is Mohammed required to do?
