what is a non-directional hypothesis
there will be a difference between…
what is a directional hypothesis
stating the outcome
what its a null hypothesis
where there is no relationship between the two variables being tested
what type of test does a nondirectional hypothesis create
two tailed test
what type of test does a directional hypothesis create
one tailed test
when should a nondirectional hypothesis be used
when there is no previous research
what are the 6 types of observations
covert, overt, naturalistically, controlled, participant, non-participant
what is a positive and negative of using covert observations
positive = reduces demand characteristics negative = no consent
what is a positive and negative of using overt observations
positive = consent given negative = high chance of demand characteristics
what is a positive and negative of using naturalistic observations
positive = high eco validity negative = high risk of confounding variables
what is a positive and negative of using controlled observations
positive = reduce of confounding variables negative = low eco validity
what is a positive and negative of using participant observations
positive = better insight into behaviours negative = details not recorded accurately
what is a positive of using non participant observations
positive = record details as they happen negative = less insight into behaviour
what is event sampling
where an observer records the number of times a behaviour occurs
what is time sampling
where an observer records behaviour at a certain interval
