Proportions: Sign test (binomial test)The sign test is equivalent to a test that the probability π of an event in the populations has the value π0 = 0.5. It is identical to the special case π0 = 0.5 of the Proportion (binomial test): Difference from constant (one sample case) test. For a more thorough description see the comments for that test.
Effect size indexThe effect size index is g = π − 0.5.
Cohen (1969, p. 142) deﬁned the following effect size conventions:
small g = 0.05
medium g = 0.15
large g = 0.25 .
