Hypotheses Flashcards
What is a hypotheses
A statement of what you believe to be true
What is a directional hypothesis
It states the kind of difference between two conditions or two groups of participants higher lower faster slower etc
What is a nondirectional hypothesis
It simply states that there is a difference between two conditions or two groups of participants
Is this non-directional or directional? Participants gain higher concentrations scores when listening to soft noise than when listening to loud noise
Directional
Is this directional or nondirectional? Concentrations scores are different when the task is performed with a soft or a loud noise?
Nondirectional
What is a one tailed hypothesis?
It is the same as directional
What is a two-tailed hypothesis
It is going in both directions and is the same as a nondirectional hypothesis
What is an experimental hypothesis
This is the hypothesis for an experiment
What is research hypothesis
This is the hypothesis written for any other kind of study
What is alternative hypothesis
This is just another term used the hypothesis it is the alternative to the null hypothesis
What is a null hypothesis?
This is a statement of no difference or no relationships for example there is no difference in the concentration levels of participants in the loud and soft noise conditions
What is the abbreviation for the alternative hypothesis
H1
What is the abbreviation of a null hypothesis?
H0
Why have directions?
Psychologists sometimes use a directional hypothesis instead of a directional one because it makes sense to expect one condition to be better than the other example when thinking of the noise and concentration experiment we might that loud noise would reduce concentration therefore it makes sense to use a directional hypothesis
