or by using technology (calculator. or software). The essential reasoning of a significance test is as follows. Suppose for the sake of argument that the . null hypothesis. is true. If we repeated our data production many times, would we often get data as inconsistent with . H. 0. as the data we actually have? Data that would rarely occur if . H. 0

Use a random number generator (like a coin or calculator) where there are two outcomes (like heads = A and tails = B, or 0 = A and 1 = B). In blocks with two windows, use the generator once on the first numbered window, assigning it to the correct treatment (A or B). Then the other window will be the opposite treatment.
