Q

labortory

A

is a controlled enviroment , it controls extraneous variables and uses standarised procedures so that proces hugh valiidty resukts .
one weakness is particoant know they are being studies and so they might chnage their behavior so thta produces less valuable

Q

field experiment

A

is when the iv is manipulated by the reaercher
one strength is that it better tahn labartory because particapnt dont know they are being studies ….
one weakness us that controlling the extranus can be diffcult also there is lots of ethicsl issues

Q

natural experiment

A

is when the iv is not manipulated by the experimenter
and so one strength it produces valid result as it involves real world variable
one wekaness is that there is less oppurtunites so less chnaces of doung tje experminets …

Q

indepernt group

A

is sectioned into two group each group is exposed to a differnt level of the iv
order effects is not a problem but
partaicpant varaiable can be a problem …
this can be fixed by allocaton to condition ….

Q

repeated measures

A

is wheb all the particpant are exposed to all of the iv
paraticpant variable is not a problem …
requires few partcipants
order effects is a problem so then they use counterbalamcing …

25
what is an ethical issue
is the conflict in the particpats rughts and the valuable results that the researcher wnats to get
26
what is informed conesent and how can u deal with it
informed consent is when the particaont shoulkd know the purpose of te study and what about the researcher should give them a letter ...
27
deception
particpant hsould be lied or misled by the aims of te study ...
28

partcipant shoud able to control the information about tjemsevels
29
confidentality

30
what is the BPS guidelines
its a code conducted for UK psusholgiscts to follow
31
what are the two types of data that we can collect
quantitauve and qualitative
32
what is quantitave
the data is in numbers ...
33
qualittaive
the data is in form of words
34
A03 for quantiatve
one strength easy to analyse , draw conclusions easier , can be interpreted into graphs one wekaness it lacks qualittaive and depth of thhe particpant thoughts so its not that valid
35
A03 FOR QUALITATIEV
one strength is that it has high valididty and so it has in depth of thoughts and feelings one wekaness its hard to analyse as you can get so much infor
36
what is primary data
primary data is data obtained by first hand the researhxer dies eveyrthung
37
seconday data
the data is second hand it akreadsy exists
38
A03 for primary
one strength is that it suits the aims of the researcher .... one weakness is that takes alot of time ...

its an indepth invertsigation about a perosn or something they are longituidnal theyw nat to see how the behaviour chnages over time and produces lots of qualittaive data
50
A03 for case studies
one strength the reaserachers a reopen minded .... one wekaness its subjetve ...
51
whats an observation
where the researcher record and observes the pasrtcipant behaviotu

one strenth it has high validity . the partcipant will nto chnage thei behavior and so that produces a higher validity eslts than other one wekaness is that ethical issues ...
59
what is reliabilty
its te meaure of consistency
60
does qualituve or quantitve tend to be reliable
quantitave tends to be more reliable like types of eperiment ( labortory experiment )
61
why does labortory experiment viewed as a reliable method
as its very controlled it can be repeated very easily uses stamdarised procedures controls EV
62
why does fied experiment is not reliable
loses control over the EV so reliablity can be diffcut
63
how does reliabilty works in interviewes and quetsionere
interviews : the same perosn needs to ansswer the same answer when they were questioned before if not then its not reliable questionaie because its closed questione it will be more reliable
64
reliabilty in observation studies
interobserver reliabilty : is whentwo researchers have an agreeemnet to look at the same sequece of behavior
65
what about reiabulity in qualittave
qualitave are less reliable case studes are diffult to repeated even with unstructured interviews
66
what is valididty
the results " refelcts " to whats really out there
67
sampling methods in validity ?
the representaiveness sis low in opuuritunity sampling but hig in starified sampling
68
experimental desgns - validity
repeated meaures should be dealth with counterbalacing independent groups : allocation to conditin
69
validity in quanitiavtve
laborotry there s high control but the parcipants awarness that they are being studdied chalnge validity field can sometimes lose control over EV but it seen more natural questionieress have a low validity
70
qualittauve methods validity
