The choice of symbol depends on the wording of the hypothesis test. To avoid this bias, scientists test a null hypothesis that states there is no correlation. According to the words used in the problem, the claim will be with the Null Hypothesis (H. 0) or Alternative Hypothesis (H. 1).

For the example just given, the null hypothesis would be designated by the following symbols: H 0: µ 1 - µ 2 = 0 or by H 0: μ 1 = μ 2. Although the symbols for the null hypothesis and alternative hypothesis -- sometimes called the alternate hypothesis -- do not exist as special characters in Microsoft Word, they are easily created with subscripts.The alternate hypothesis is symbolically represented by a capitalized "H," followed by a subscript "1," although some researchers prefer an "a."
