An observational technique in which the observer records behaviours in a given time frame e.g. Noting what they are doing every 30 seconds

A systematic method for recording observations in which individual behaviours are given a code for ease of recording

Q

Inter observer reliability

The extent to which there is agreement between two or more observers involved in observations of a behaviour. Rule=total no of agreements/total number of observations=>80% then the data has high inter-observer reliability

62
Q

Observer bias

A

In observational studies, there is the danger that observers might ‘see’ what they expect to see. This reduces the validity of the observations

A sample of participant produced by selecting people who are most easily available at the time of the study

65
Q

Random sample

A

A sample of participants produced by using a random technique such that every member if the target population being tested has an equal chance of being selected

66
Q

Stratified sample

A

Groups of participants are selected according to their frequency in the population in order to obtain a representative sample. Groups are selected from the target population that needs to be represented, individuals sampled from the group. Individuals are chosen randomly

67
Q

Quota sample

A

Groups of participants are selected according to their frequency in the population. Groups are selected from the target population that need to be represented. Individuals are chosen from this group(not chosen randomly)

68
Q

Systematic sample

A

A method of obtaining a representative sample by selecting every 5th or 10th person. Can be random sample if the first person was chosen randomly

69
Q

Target population

A

The group of people that the researcher is interested in.

70
Q

Volunteer bias

A

A form of sampling bias because volunteer participants are usually more highly motivated than randomly selected participants

71
Q

Volunteer sample

A

A sample of participants produced by a sampling technique that relies solely on volunteers to make up the sample

A

A research method or technique that involves a face to face real time interaction with another individual and results in the collection of data

Q

Open questions

A

Questions that invite the respondents to provide their own answers rather than select one of those provided. Tend to produce qualitative data

76
Q

Structured interview

A statistical term indicating that the research findings are sufficiently strong for us to accept the research hypothesis under test
