Question

Sally decides to conduct an exact replication of an experiment she has just read about in a research journal. If Sally does not obtain the same results reported in the original study, what might be responsible for her failure to replicate the results?

The replication attempt was flawed.

Any of these

The original author omitted an important aspect of the procedure.

The original results represent a Type I error.

Answer 1

Correct answer: Option 4

Option 1 is incorrect because the question already mentions that Sally conducts an exact replication.

Option 2 is incorrect because the authors of any research paper ought to give a detailed and thorough explanation of their study.

Option 4 is correct because, Type I error contains wrongly rejecting the null hypothesis. Although the probability of such an error is restricted to very small values which are atmost 5% or 10%, the chances of commiting this error are still positive. And hence it is possible thta the original results represent a Type I error.
