type 1 error

Type 1 errors are those errors resulting from wrongly rejecting Ho - the null hypothesis - when it is in fact true (i.e. a false positive result).
Usually the risk of this is given by a probability alpha, written n < 0.05 for the level of chance of a type 1 error to be less than a twentieth.
