Hypotheses
A statement that is made at the start of a study and clearly states the relationship between variables as stated by the theory
In a Directional hypothesis the research makes clear the sort of difference that is anticipated between two conditions or two groups of people. For this reason, directional hypotheses include words like more or less, higher or lower, faster or slower etc. An example is 'People who drink SpeedUpp become more talkative than people who don't.
In a Non-directional hypothesis, it simply states that there is a difference between conditions or groups of people, but the nature of the difference is not specified. An example is 'People who don't drink SpeedUpp differ in terms of talkativeness compared with people who dont drink SpeedUpp
