When several tests are used together, the cumulative probability value (p-value) is influenced by the probability values for each test.
Assumptions: The tests are independent of each other.
If the tests have a similar p-value, then:
overall p-value for a number of tests used together =
= 1 - ((1 - (p value for test))^(number of tests))
If the tests have different p-values, then:
overall p-value for a number of tests used together =
= 1 - ((1 - (p value for first test)) * (1 - (p value for second test)) * ….*(1 - (value for last test)))
