Q

What is a scattergram?

A

a graph that is used to find a relationship between two categories of data

30
Q

What is mean, median and mode?

A

Mean - statistical average, add up all scores and divide by total amount of scores
Median - middle value of data set, putting them in order and finding the middle score, if there are 2 middle scores then add them together and divide by 2
Mode - Most frequent number

31
Q

What is standard deviation?

A

A graph where the values are spread across around the mean, most powerful as it takes all measurements into account

32
Q

What is a co-variable

A

variable in a correlation

33
Q

What is a correlation co-efficient

A

Tells strength (how close is it to 1) and direction (+ or -) of a correlation in a graph

34
Q

What are the steps for a sign test?

A

step 1 - convert data to nominal data by + - or = e.g. 100-122 is negative
step 2 - Total up the + and - then disregard the =
step 3 - identify calculated value that is the least frequent sign known as S
step 4 - compare S value to critical value table, find out if the hypothesis is non directional or one directional, remember accepted level of probability which is 0.05

35
Q

What is a repeated Measures experimental design?

A

Same participants used in both conditions (order effect)

36
Q

What is an independent groups experimental design

A

Participants allocated to different groups representing seperate conditions (cant control variables in participants)

37
Q

What is a matched pairs design?

A

participants are closely matched and placed into certain conditions. (time consuming)

38
Q

What are order effects and how can it be managed?

A

Order effects are where you perform better or know more about an experiment as you have experienced and practiced it before. This can be seen in repeated measures experimental design.

Order effects can be managed through counterbalancing to create equal effect in both conditions by changing those conditions. This can be done by switching the order of the conditions done.

39
Q

What is Oppurtunity Sampling?

A

Participants are sampled when they are available such as a person who is not at work.

40
Q

What is a random sample?

A

Sample where participants are randomly grabbed usually to fill a quota of a target population

41
Q

What is a stratified sample?

A

Selecting participants based on a subgroup of characteristics e.g. age or gender.

42
Q

What is a systematic sample?

A

Collecting every nth person to avoid bias in a target population e.g. 5th 15th 25th 35th

43
Q

What is a volunteer sample?

A

A sample where participants actively volunteer for your research. This is usually done if theyre interested or if they are going to be rewarded.

44
Q

What is a biased Sample?

A

Systematic distortion in the collection of participants which is usually done based on judgement which lowers generalisability and representiveness.

45
Q

What is generalisation?

A

Applying findings of a study to the general population making an assumption of the population.

46
Q

What is internal validity?

A

accuracy of data within the experiment

47
Q

What is external Validity?

A

How accurate research is outside of research

48
Q

What is ecological, population and temporal validity?

A

ecological - how accurate it is to social environments
Population - How accurate it is to views of the general population.
Temporal - How accurate it is to the current time period

49
Q

What are investigator Effects?

A

Cues from investigator to encourage certain behaviour

50
Q

What is demand characteristics?

A

Behaviour that is thought to be demanded so you can be helpful to the researcher

51
Q

What is social desirability effects?

A

Giving answers desirable by the researcher

52
Q

What is a single blind and double blind procedure?

A

Single blind procedure - Patients are unaware of the test being conducted
Double Blind procedure - Participants and researcher unaware of the test being conducted

53
Q

What is a Pilot Study?

A

Small scale study done to find problems with experimental design, instructions and the methods, can also check for ethical issues.

54
Q

What are the main ethical issues?

A

Deception, protection from harm, confidentiality, right to withdraw data and privacy

55
Q

What can be done to deal with ethical issues?

A

Deception - Debriefing
Protection from harm - Stop study and compensate the participant and give them help.
Right to Withdraw - Inform participant at the start, middle and end of study to withdraw data if needed.
informed consent - Fully explain research intentions
Privacy/confidentiality - Avoid using names in study, dont study unless there is informed consent.

56
Q

What is time sampling and event sampling in an observational design?

A

Time sample - recording behaviours in a given time frame
Event - recording behaviours during a certain event

57
Q

What are the strengths and weaknesses to time sampling and event sampling

A

Time - less time consuming due to less observation however it may not be representative of target population.
Event - Useful in recording occasional behaviour however certain behaviours may be too hard to record, also time consuming.

58
Q

How can you assess reliability for observations, self-report techniques and experiments?

A

Observations - use multiple observers and record evidence for inter-observer reliability. Can be fixed if categories are operationalised
Self report techniques - test retest, reduce ambiguity of questions
Experiments - test retest or blind procedures

59
Q

What is retest reliability?

A

used to assess reliability of questionairres by assessing someone on two seperate occasions.

60
Q

What is face validity?

A

whether the measure is determined to measure what it is supposed to measure.

61
Q

What is concurrent validity?

A

extent to which a psychological measure relates to an existing similar measure

62
Q

What are the steps for content analysis?

A

1) what data will you select
2) how you code your data e.g. behavioural categories
3) how is the data represented e.g. is it numerical or worded

63
Q

What is Nominal Data

A

Data where something is named e.g. gender such as male or female

64
Q

What is Ordinal Data

A

Data where behaviour is ranked and categorised

65
Q

What is interval data

A

Data which is continous and the difference is standardised and meaningful

66
Q

What is Empiricability as a feature of science?

A

Use of controlled, objective, quantitative observation to prove a theory

67
Q

What is objectivity as a feature of science?

A

When research is free from bias or personal opinion and is not subjective.

68
Q

What is replicability as a feature of science?

A

Are the results reliable and will you get the same answer if done again

69
Q

What is Falsifiability?

A

Whether an experiment can be proven false, is testable and can be measured objectively.

70
Q

What is a paradigm shift?

A

When there has been massive changes in a concept or experimental method.
