What are significance/alpha levels and how does using a one versus a two tailed test affect significance levels?

  • Psychology/Math -

    Alpha levels are the probability of rejecting Ho, when Ho is true. If you are choosing P = .05, a two tailed test will be looking for .025 in either direction. If a one-tailed test, you will be looking for .05 in one direction.
