experimental method

• The structure of a directional hypothesis is: People who do condition a are more/ less than condition b.
• People who do condition a differ in terms of theory compared to the people who do condition b.
• directional hypothesis is when the researcher makes a clear anticipation between the two condition groups. It describes the  direction of the relationship/ difference. It must include words such as faster/ slower, less/more, higher/ lower. 
• non-directional hypothesis states the difference between the condition of the two groups and the nature of the difference is specified. It also does not describe the direction of the relationship or difference.
•  hypothesis is a statement that is precise and testable, and it describes the relationship between the variables. There are two types of hypotheses : a directional hypothesis and a non directional hypothesis.
• Operationalisation is there clearly defining how the variables will be measured, and it helps to make sure that the variables are measurable. For this you could test the hypothesis by testing the amount of words spoken after a certain amount of conditions a or b within a set time period. Then you would compare the amount of words spoken between the two levels of conditions.
