... • Normal/Large Sample: Both population distributions (or the true distributions of responses to the two treatments) are Normal or both sample sizes are large (n1 ≥ 30 and n2 ≥ 30). If either population (treatment) distribution has unknown shape and the corresponding sample size is less than 30, use ...

... • It’s safer to first consider the variability of each sample, the pattern of any outliers, the shape of the distributions. • Then it may be safe to assume a normal distributions; but not always. • So, we’ll also discuss approaches to answering these questions when we’re not comfortable with the ass ...

The best explanation for this result is that A) the placebo effect is present, which limits statistical significance. B) the sample size is too small to determine if the observed increase cannot be reasonably attributed ...
