A null hypothesis is never proven by such methods, as the absence of evidence against the null hypothesis does not establish it. In other words, one may either reject, or not reject the null hypothesis; one cannot accept it. ...

Causality and research design • Causality is often difficult to determine—wait for the next slide—that’s that’s why research design is important. • An experiment is the gold standard. • If a treated subject and a control subject are the same in every respect (as they are in a perfect experiment), w ...

... c. False: In repeated samples, around 95% of the 95% confidence intervals (CI) will contain the population mean. Another way to think about 95% CI is if the same study were repeated 100 times then the mean of 95 of these 100 studies would lie somewhere within the 95% CI. d. False: is approximately e ...
