“… displays evidence of all three errors: The number of synchronous instances is simply too number of being statistically significant (Mistake I), among the four synchronous scenarios has an incorrect First onset distinction which, when corrected, triggers the initial mean onset change to be higher than the ultimate necessarily mean onset difference (Error II), and a number of topics can have withdrawn from the experiment since their cycle habits wasn't Assembly the expectations with the investigators (Mistake III).
