17
Q

What is an aim?

A

A statement of what is going to be studied. Not a prediction

18
Q

What is a hypothesis?

A

A bold statement written before research is carried out. Makes a prediction of what will happen. Fully operationalised.

19
Q

What is a directional (one tailed) hypothesis?

A

Will have specific outcome that you expect to happen. E.g. People will do better in on condition that another

20
Q

What is non directional (two tailed) hypothesis?

A

Less certain but know something will happen. Not sure what. E.g. There will be a difference between ps in one condition and ps in another condition
