Q

what is the process of a peer review?

A

researcher sends their report to the editor of the journal, who sends the report out to 3 psychologists (referees) who are considered experts in the area

referees analyse and comment on whether the editor should include it in the publication

referees are unaware of the researchers identities to prevent bias but it is possible to guess

Q

what are the pitfalls of a peer review?

A

reports don’t tend to get published if they don’t support a hypothesis. this can be called the ‘file-drawer’ problem, as if your results are not significant, then researchers keep them in their filing cabinet and never get written up for publication
Popper says this is unfortunate as they never have the chance to be falsified

issue of bias as certain institutions have more chance of getting published such as a university

referees volunteer to be involved and it looks good on their CV

Q

why is it important to get published in a peer-reviewer journal?

A

articles published in a peer reviewed journal are of greater merit than those that aren’t

research will only be published if it makes an important contribution to the scientific field and the research has been methodologically and ethically sound

Q

how to carry out content analysis?

A
data is collected 
                                   ↓
researcher examines the transcribed data to familiarise themselves with it
                                   ↓
the researcher identifies coding units
                                   ↓
data is analysed by applying coding units
                                   ↓
tally is made of each time a coding unit
                              appears

Q

what is an example of a coding unit?

A

for each time a serial killer mentions their mother as a reason for their behaviour could be coded as ‘M’

Q

how do you check the reliability of content analysis?

A

use inter-rater reliability

both researchers use the same coding units and carry out co tent analysis independently

Q

what is the process of thematic analysis?

A

reading a transcript and identifying key themes and giving each a short-hand code (still using a coding system) e.g. if a theme is mother as a reason for behaviour, the code could be ‘mum’

the read through the transcript again and give each code a colour and highlight each time you see it

then write a report, using each theme you identified as a subheading in a written report, explaining why each factor was important

use quotes to support what you say

Q

what are the strengths of thematic analysis?

A

qualitative so more in depth

26
Q

what are the weaknesses of thematic analysis?

A

relies on interpretation from researcher so potentially bias

can’t carry out inter-rater reliability

27
Q

what is the advantage of using the mean?

A

most powerful as it takes into account all scores

28
Q

what is the disadvantage of using the mean?

A

can be distorted by outliers

29
Q

what is the strength of using the median?

A

unaffected by outliers

30
Q

what is the weakness of using the median?

A

only takes into account the middle number(s)

31
Q

what is the strength of using the mode?

A

unaffected by outliers

32
Q

what is the weakness of using the mode?

A

unrepresentative as it can be affected by the change in one score

33
Q

what are the measures of dispersion?

A

range

standard deviation

34
Q

what is the strength of using the range?

A

quick to calculate

35
Q

what are weaknesses of using the range?

A

does not provide any idea of distribution of values

does not take all data into account

seriously affected by outliers

36
Q

what is standard deviation?

A

measure of variability of the mean

large s.d = there was much variation around the mean

small s.d = data was closely clustered around the mean

zero = all data values were the same

37
Q

where is the mode on a distribution graph?

A

always tallest

38
Q

where is median on distribution graphs?

A

always in the middle

39
Q

what is mean on distribution graphs?

A

always shortest

40
Q

if the mean is smaller than the median, where on the distribution graph does it go?

A

left

41
Q

if the mean is bigger than the median, where on the distribution graph does it go?

A

right

42
Q

what is nominal data?

A

when data falls into separate categories
each piece of data falls into one category

eg smokers and non smokers

43
Q

what is ordinal data?

A

the data is ordered in some way
also includes attitude scales

eg ordering people in terms of height

44
Q

what is interval data?

A

data is measured using units of equal intervals such as minutes, seconds, inches, centimetres etc

eg measure everyone’s height so you know the difference between them

45
Q

in probability, what does 0 or 1 represent?

A
0 = no influence of chance
1 = complete influence of chance
46
Q

what does p<0.1 mean?

A

10% chance of results being a fluke

47
Q

what level of significance do psychologists use?

A

p<0.05 regarded as the minimum level of significance for regarding results as significant

48
Q

when would a 1% significance level be used?

A

medical tests

49
Q

what is a type 1 error?

A

when you accept the alternative hypothesis but results aware actually a fluke (false positive)

50
Q

when is a type 1 error most likely to occur?

A

when p<0.1 is used

51
Q

what is a type 2 error?

A

when you accept the null hypothesis but results were actually affected by the IV (false negative)

52
Q

when is a type 2 error most likely to occur?

A

when p<0.01 is used

53
Q

what does carrots should come mashed with swede under roast potatoes mean?

A
chi2
sign
chi2
mann whitney 
wilcoxon
spearman’s rho 
unrelated t test
related t test
pearsons r
54
Q

what does concurrent validity mean?

A

when we create a new test, we get participants to complete the new one and a well-established one to see if results are similar

55
Q

what does face validity mean?

A

when looking at first glance at how they’re measuring the concept, does it look valid?

56
Q

what does ecological validity mean?

A

does this apply outside of the study?

57
Q

what does temporal (historical) validity mean?

A

do the findings from previous research hold over time?

58
Q

what does population validity mean?

A

how far the study can be applied outside of the study to other groups

59
Q

what is the procedure of a sign test?

A

record both conditions in a table numerically

write the difference in scores in the difference column

in the end column write ‘+’ for an increase, and ‘-‘ for a decrease, and cross out scores that do not change

count the +’s and -‘s and the LOWEST value is your calculated statistic/value, represented as S=_______

60
Q

to be significant, what must the value of S be in proportion to the critical value

A

less than or equal to
