Q

What is statisfied sampling?

A

Dividing target population into important sub categories. Selecting members in proportion that they occur in the population. EG] 2.5% of British are of an Indian origin, so 2.5% of your sample should be Indian …

Q

What is a strength of volunteer sampling?

A
  • Convient
  • Ethical if it leads to informed consent
  • Access to a large variety of participants, which leads to more representative data samples

25
What is a directional question? [1 tailed]
- States the direction of the difference or correlation - Close ended - States what the group will do
26
What is social desirability?
When a participant changes their behaviour or response to be seen in a better light [positive view].
27
What are older effects?
Effects that occur due to the order the participants experiences during the conditions.
28
What is response bias?
When a participant responds to a question in a pattern. EG] A,B,C,A,B,C...
29
What is a null hypothesis?
- Opposite to a null hypothesis - Predicts no significant difference or correlation - Any differences will be due to chance - One will be rejected, one will be accepted
30
What is correlation?
A way of analysing the relationship between two co variables. It will be used to gain data from other research methods, questionnaire or observation. Presented with scatter graph.
31
What is a strength of a correlation?
Identifying correlation can determine whether future additional research needs to take place.
32
What is a weakness of a correlation?
- Researchers can't establish cause and effect between the 2 variables - Can't assess impact of additional variables
33
What is alternate/alternative hypothesis?
The significant difference or correlation you expect to observe.
34
What is an observation?
Researcher watches and records participants behaviour without interfering. They can be naturalistic or structured. Theyccan be overt or covert.
35
What is a strength of an observation?
Naturalistuic observations are high in ecological validity.
36
What is a weakness of an observation?
- Structural observations may lack ecological validity | - Bias issues
37
What is an interview?
Interviewer verbally asks participant a series of questions, either face to face or via phone. They can ask open or closed questions in order to gain quantitative data or qualitative data.
38
What is a strength of an interview?
If structure interview is used, data is high in reliability as interview can be easily replicated.
39
What is a weakness of an interview?
When unstructured is used, it's difficult to replicate.
40
What is a field experiment?
Takes place in an environment that's natural to participants.
41
What is a strength of a field experiment?
- A natural setting means that data ia high in ecological validity - Participants behaviour will be true to everyday life
42
What is a weakness of a field experiment?
- Researcher has limited control on extraneous variables | - Results shown can be effected by environment
43
What is a lab experiment?
They take place in an artificial controlled environment.
44
What is a strength of a lab experiment?
Experimenter can control extraneous variables
45
What is a weakness of a lab experiment?
Behaviour shown by participants may not reflect their everyday behaviour, meaning data is low in validity.
46
What are conditions?
Different variants of the independent variable
47
What is a dependent variable?
The variable affected by the independent variable, which is measured by the researcher.
48
What is a hypothesis?
A prediction about the results of a study. It's a testable statement, that can be supported or rejected by research.
49
What is demand characteristics?
When a participant changes their behaviour or response in order to please the researcher. Mainly happens when participants try and guess the aim of the research.
50
What is an extraneous variable?
Variables that MIGHT impact the results of a study. [DV that aren't the IV].
51
What is a confounding variable?
Variables that DID impact the results of a study [DV] that aren't the IV.
52
What is an independent variable?
The variable changed by the researcher.
53
What is quantitative data?
Data in a numerical form.
54
What is qualiltative data?
Non-numerical data in a descriptive form.
55
How can you test a hypothesis?
- Lab experiment - Interview - Observation - Questionnaire - Field experiment - Case study - Correlational study - Analysing secondary data
56
What is a non-directional study? [2 tailed]
- States there will be a difference or correlation but doesn't suggest the direction - Open ended - Could go any way
57
What makes a hypothesis SOFT?
- Specific - Operationalised - Falsifiable - Testable
58
What is a C and C writing frame?
Claims and components
59
What is SODA writing frame?
- Supporting evidence - Opposing evidence - Different theory - Applications
60
What is independent groups design?
When different participants are used in each condition of the independent variable.
61
What is a participant variable?
The differing characteristics that may impact how a participant responds in an experiment.
62
What is a situational variable?
They can be situational [to do with the setting or task] or ppt [to do with the sample] variables.
63
What is demand characteristics?
When a participant changes their behaviour or respons in order to please the researcher. This happens when they guess the aim of the research.
64
