Directional hypothesis: A directional (or one tailed hypothesis) states which way you think the results are going to go, for example in an experimental study we might sayParticipants who have been deprived of sleep for 24 hours will have more cold symptoms in the following week afterexposure to a virus than participants who have not been sleep deprived; the hypothesis compares the two groups/conditions and states which one will .have more/less, be quicker/slower, etc.
