reliability

Question 1

what is reliability

Answer 1

-when a measurement tool is used and gets the same results every time
-whether something is consistent

Question 2

what result should the tool produce if measuring the same thing

Answer 2

the same result on every occasion

Question 3

if the results of the same test is different, what must we ensure

Answer 3

that its the thing we are testing that’s changed not our tool

Question 4

if the exact same results are difficult to obtain, what does psychology use instead

Answer 4

-a strong positive correlation

Question 5

what do you need in order to assess reliability

Answer 5

-an observational research study using more than one observer

Question 6

when is data unreliable between observers

Answer 6

if different observers provide significantly different observations of the same behaviour

Question 7

how can observer reliability be assessed

Answer 7

-by correlating the data provided by the observers
-High correlation = high agreement = reliable test

Question 8

how to improve the reliability of observers

Answer 8

-train observers in techniques being used
-make sure everyone agrees with them

Question 9

what can you do to improve the reliability of categories

Answer 9

-ensure they are correctly and objectively operationalised
-means behaviour being observed can ONLY be that behaviour

Question 10

what is reliability mainly referred to in psychology

Answer 10

-observations

Question 11

how to conduct inter-rater reliability (INTER acryonym)

Answer 11

I- involve a third observer
N- name categories you will use
T- tally behaviours observed separately
E- establish if there’s a correlation
R- reliability is +0.8 or more
