This refers to the consistency of the findings.
internal reliality and how you would test it
refers to the consistency of the results of a test across items within the test. do split half method to see if you get the same results in the second half of the test.
external reliablity and the test for it
refers to the extent to which the a test cores varies from one to another. for this do a test retest to see if the result you get on the first test is the same as what you would get on another test.
to avoid observer bias. two observers need to observe behaviour and correlate them to see if they are similar.
validity and things that effect it
this is seeing how accurate a piece of research is at measuring what it says its meauring. if there is lots of extraneous variables then the IV may be effected by it.
what is high internal validty
if there are high degrees of control and no extraneous variale it has high internal validity.
if the research has been done in a real life setting it has high external validty so it can be geneeralised
how good the test looks to be at what it is supposed to be testing
where a test measures the behaviour it sets out to measure
where a test give the same result as another study which claims to measure the same behaviour
how much one measure predicts the value of another measure
how accurately the test measurees behaiour that can be generalised to the wider population.
where the test can be conconsidered to replicate real life settings
where the particpants must select which statements apply to them
where the particpants are asked to rate how they feel about something
semantic differrential scale
where they are asked to rate items on opposing pairs
the observer record every behaviour that ocurrs
time point sampling
where the observer records things at fixed intervals
time event sampling
where a fixed period of time is set forr the observation
§ is used when the same participants take part in each experimental condition. It involves the first half of the participants taking part in the first part of the experiment and the second taking part in the second and then switching to eliminate order effects.
one tailed hypothesis
predicts a change and says in which way the direction will go
two tailed hypothesis
will predict a change but wont say in which direction it will go in
the capacity to prove something wrong and prove the hypothesis wrong
having general laws to stick to. eg; ethics
rules for parametric testing
variances should be equal
shows catagories of behaviour and how oftern the occur. eg frequency table
shows each individual scores so they can be ranked
tells you differnces between individuals with measurement such as time.
