Recall That Doing Many Statistical Tests Increases the Overall Chance

Essay

Recall that doing many statistical tests increases the overall chance of a Type I error. Consider a situation in which we test 1,200 genes for their influence on a measured factor. If we use an a = 0.05 threshold for each test and obtain 83 significant results, how would we interpret this, and what would the next step be? Be sure to make a quantitative statement about these results in reference to the technical phrase "false discovery rate" in your answer.
