Alpha (α) is conventionally set at .05 by social researchers, which means there is a 5% risk of concluding that a difference exists when there is none. Alpha does not increase as sample size decreases; instead, it is a predetermined threshold. Also, no level of α can provide absolute certainty due to the inherent possibility of Type I errors.
