aims and hypothesis

Question 1

aim

Answer 1

-clearly phrased general statement about what investigator intends to research
-can include purpose study

Question 2

hypothesis

Answer 2

-precise testable statement including levels of IV and DV (or both co variables in correlational study)

Question 3

operationalisation

Answer 3

-operationalised variables carefully stated, stating exactly how measured
e.g DV would be ‘number of word recalled’ not ‘recall’
-IV needs to be clearly stated in both conditions

Question 4

null hypothesis

Answer 4

-states no change in DV as result of change in IV

Question 5

alternative hypothesis

Answer 5

-states there is a change in in DV due to change to IV

Question 6

two types alternate hypothesis

Answer 6

-directional
-non directional

Question 7

non directional hypothesis

Answer 7

-states there is a difference in measurement of DV as result of manipulation of IV but not direction the results will go
e.g there will be a difference between

Question 8

directional hypothesis

Answer 8

-states there is a difference between the measurement of the DV as a result of manipulation IV and says which direction result will go
e.g there will be an increase in this as this happens

Question 9

when will a researcher use directional hypothesis

Answer 9

-if there is previous research that suggests which way the results are most likely to go
