What is a benefit of using random sampling in an experiment? A. It can help control the effects of lurking variables. B. It can allow us to draw cause-and-effect conclusions. C.

Which one of the following statements is correct? A. The 1.5 x IQR rule is used in order to determine if a sample was randomly selected from the population. B.

We say we have bias if our sampling method leads to a systematic overestimate or underestimate of the population parameter. What is a benefit of using random sampling in an experiment? A.
