Q

What are the strengths and weaknesses of the self selecting sampling method?

A 
Strengths -

Q

What are the strengths and weaknesses of the Opportunity sampling method?

A

Strengths -
.Quick to gather participants

Q

What are the strengths and weaknesses of the Snowball sampling method?

A

Strengths -
.Easy as only requires finding a few participants before they recruit the rest
.relatively cheep as no advertising
Weaknesses -
.Biased as all participants likely to know each other and therefore have many similarities
.May not get enough participants

Q

What is time sampling?

A

Q

What is researcher / observer bias?

A

This occurs when a researcher is expecting to see a particular behaviour, and subconsciously may be biased ad record the data inaccurately.

25
What is a Quasi experiment?
Iv is naturally occurring not manipulated by the researcher.
26
What is repeated measures design ?
Using the same people in both conditions
27
What is independent measures design ?
Using different people in each condition
28
What is Matched groups design ?
Using different people in each conjoint but matching participant based on certain characteristics to reduce individual differences being a factor.
29
What are participants extraneous variables?
Characteristics of the individual participant that may effect the result
30
What are situational extraneous variables?
Any features of the research situation which could influence the result
31
What are demand characteristics?
Where participants may act in a way they consider expected of them, skewing the data of the study.
32
What is an alternative hypothesis ?
A hypothesis that predicts the IV will effect the DV
33
What is a null hypothesis?
A hypothesis that predicts there will be no effect and that any effect will be due to chance.
34
What is a two tailed hypothesis ?
It predicts the the Iv will gave a significant effect on the Dv, but it does not predict the direction that it will go in.
35
What is a one tailed hypothesis ?
It predict's not only that the Iv will have a significant effect on the DV, but also the direction this effect will go in.
36
What is quantitative data ?
Numbers, measurements and percentages.
37
What is qualitative data ?
Descriptive words meanings and pictures.
38
What are rating scales?
Will measure usually from 1 - 10 the extent of someones attitude towards something, eg really bad too really good
39
What are likert scales?
Uses statements and sees whether they; Strongly agree/. agree/ undecided/ disagree/ strongly disagree
40
What is a semantic differential?
Two polar opposite adjective e.g big and small with number in-between to see how far you agree
41
What is a structured interview ?
The interviewer asks the same closed questions
42
What is a unstructured interview ?
The researcher has topics to discuss, but it is more like a conversation.
43
What is a semi structured interview ?
The interviewer will have a set of questions to ask but the timing and phrasing can change, with more open ended questions.
44
What is a leading question?
Questions that lead a participant to be more likely to give a certain answer.
45
What are socially desirable answers?
Participant will give answers they think make them look good
46
What are forced choice questions?
Where participants must choose one item from the limited range available.
47
What are demand characteristics?
Participant may give answers they think the researcher wants here.
48
What is a standard response set?
Giving the same answer to all questions
49
What is nominal data?
Headcount - number of participants who do one thing over an other eg. headcount of number of males vs females eat fruit
50
What is ordinal data?
Rank order - position of an item within a group, however not measured so can't see the difference between each eg. 1st second and third
51
What is Interval / ratio level of data
Rank order + individual results, takes amount of the differences between each position based on the individual data eg. measure of concentration using 30 word word search, results = 1st 29 2nd 23 and 3rd 10
52
What is a correlational hypothesis?
Same as null and alternate, uses words significant correlation over significant difference, and in a one tailed hypothesis suggests either a positive or negative correlation.
53
What is the test for nominal, independent measures experiment ?
Chi Square
54
What is the test for nominal, repeated measures experiment ?
Binomial sign test
55
What is the test Ordinal, independent measures experiment ?

Related t-test
60
What is the test for Interval/ratio, correlation study ?

61
How do u perform a Binomial sign test?
.In the third column add a + or - to show the direction of the difference, if unchanged then don't use that participant and don't count them when working out n. .calculate the number of times your least frequent sign (+ or - ) as-rears and call this your calculate value of x. .Use the critical value table to see if there is a significant difference.

What are the strengths and weaknesses of peer review?
Strengths - .Increases credibility Weaknesses - .Researcher who reviews it may not publish
68
What is a normal or skewed graph?
Normal = middle hump Positive skewed = left Negative skewed = right

Mean Mode Median
82
What are the two types of external validity?
.Population validity (Generalisable) | .Ecological validity
83
What are the four types of internal validity?
