1
Q
Structure for 15 marker? (Generic)
A
For each element ie sampling tech. :
- knowledge and understanding
WHAT IT IS (ELEMENT) - application of elements in context of investigation
HOW WOULD USE - justification of elements
WHY - links to own experience
OWN PRACTICAL IE REPLICA GRANT
2
Q
4 main methods of investigation AND examples
A
- self report
Surveys, questionnaire’s, interviews - a correlation
Statistics (scatter graphs), ie maths based) - an observation
Watching people - an experiment
Only scientific method: lab, field, quasi
3
Q
Non- experimental methods
A
Observation techniques
Self report
4
Q
List all ethical guidelines and outline briefly what they are
A
- informed consent
Participant told what is required so can make informed decision to take part - respect
Value the dignity and worth of all ps - right to withdraw
Tell ps they have the right to withdraw including their data at any point
-confidentiality
Right to expect their information is treated confidentiality and if published unidentifiable that it’s theirs
- competence
High levels of competence + operating to function within recognised limits - responsibility
Value their responsibilities including avoidance of harm and prevention of misuse or abuse of their contributions - protection of participants
Protect ps from physical and mental harm during investigate - debrief
Ps are aware they have taken part in an investigation and provide the ps with any necessary information to complete their understanding - integrity
Value honesty accuracy clarity and fairness in their interactions with all persons - deception
Misleading of ps is unacceptable if they are likely to object once debriefed
5
Q

14
Q
Advantages of laboratory experiment
A
Highly controlled (control other factors)
15
Q
Disadvantages of laboratory experiment
A
People being observed may change their behaviour so results not always accurate - high demand characteristics
Not in natural environment, so results may vary
Short:
- not always accurate because demand characteristics
- not natural environment (low ecological validity)
16
Q
Advantages field experiment
A
Natural environment / don’t know being observed so more accurate - naturalistic
Low demand characteristics
17
Q
Disadvantages of field experiment
A
Lower control
18
Q
Advantages quasi experiment
A
Easier because variable is established (don’t need to manipulate situation)
19
Q
Disadvantage quasi experiment
A
Less flexible
20
Q
Advantages observation
A
Collect true results / behaviours - low demand characteristics
21
Q
Disadvantages observation

Time consuming
Not always covert / may know being watched
22
Q
Advantages Survey / questionnaire
A
Varied opinions
Measuring cognitions (only method)
23
Q
Disadvantages survey / questionnaire
A
May not be valid / truthful
Socially desirable responses
24
Q
Advantages correlation
A
Useful for making predictions
Pre- experiment
25
Disadvantages correlation
Can’t state cause and effect (scientific)
26
Types of sampling techniques
Random
Opportunity
Self selected / volunteer
Snowball
27
Random sampling
Every member population equal chance of appearing in sample
28
Opportunity sample
Asking people who are available at the time
29
Self selected / volunteer sample
Participant choose themselves
30
Snowball sampling
Get participants from existing ones asking friends / family / relevant people when they need a bigger sample
31
Advantage of random sampling
Usually get a range of participants from large area
Not bias
Most representative
32
Disadvantage random sampling
Not always possible / practical
Not everyone willing
Chance bias
Time consuming
33
Advantage opportunity sampling
Good way to find relevant people
Quick / easy
34
Disadvantages opportunity
Hard to get non bias / wide range sample
Likely to be ethnocentric
35
Advantages self selected
Participants most keen / willing
36
Disadvantages self selected
Most likely to obedient / certain type of people ie students
37
Snowball sampling advantage
Easy way to gain more participants
38
Disadvantages snowball
Less direct / controlled as to who takes part
39
IV
Manipulated
40
DV
Measured
41
Experiment method
What does
How
Show cause and effect
By controlling testing environment so only IV is different between 2 or more groups
42
Confounding variable
variable that influences both the dependent variable and independent variable
43
Types of experimental designs
Repeated measures
Independent measures
Matched pairs
44
Repeated measure
Same participants in each condition / group
