- In hypothesis testing, H0 always has a symbol with an equal in it, while Ha never has a symbol with an equal in it1. The choice of symbol depends on the wording of the hypothesis test. However, many researchers use = in the null hypothesis, even with > or < as the symbol in the alternative hypothesis1.Some Greek letters used in hypothesis testing include2:
- α “alpha” = significance level in hypothesis test, or acceptable probability of a Type I error (probability you can live with).
- β “beta” = in a hypothesis test, the acceptable probability of a Type II error; 1−β is called the power of the test.
- μ mu, pronounced “mew” = mean of a population.
- ν nu: see df, above.
