Type II error (β) Stating that there is not an effect or difference when one exists (null hypothesis is not rejected when it is in fact false).

β is the probability of making a type II error. β is related to statistical power (1 – β), which is the probability of rejecting the null hypothesis when it is false.

Also called false-negative error. β = you blindly let the guilty man go free.

If you increase sample size, you increase power. There is power in numbers.
