approach for studying the meanings, patterns, and experiences of a defined group in a holistic fashion. Aims to produce a detailed description of how a particular group operates, based on observation of, and often participation in, the group. Describing cultures

39
Q

the researcher does not become, nor aims to become an integral part of the system or community they are observing.

40
Q

Participant Observation

A

researcher is or becomes a part of the team, community, or cultural group they are observing.

41
Q

Phenomenolgy

A

study subjective phenomena in the belief that critical truth about reality are grounded in people’s lived experiences. Goal is the fully describe lived experience and the perceptions to which it gives rise.

42
Q

Grounded Theory

A

focused on generating theoretical ideas from the data….rather than having these specified beforehand. Theory emerges from the data.

43
Q

sampling

A

the process of selection a portion of the population to represent the entire population

44
Q

sample

A

a set of units observed from the all possible units. Subset of the population.

45
Q

representative sample

A

a sample that represents the characteristics of the population as closely as possible

46
Q

sampling bias

A

sample is not representative of the population or inappropriate for the question asked. A consistent error that arises due to the sample selection.

47
Q

probability sampling

A

members of the population have a known chance (probability) of being selected.
Types: Simple random sampling, stratified, multistage, systematic

48
Q

Non-probability sampling

A

instances in which the chances (probability) of selecting members from the population are unknown.
Types: Convenience, quota, purposive, snowball.

50
Q

snowball sampling

51
Q

Quota Sampling

52
Q

Purposive Sampling

A

the conscious selection of certain participants or elements to include in a study

53
Q

Simple Random Sampling

A

flipping a coin or choosing from a hat

54
Q

Stratified Random Sampling

A

The population is separated into homogenous groups and a sample is taken from each, then subsamples are merged in to one sample.

55
Q

cluster sampling

A

population is divided into similar groups or clusters. These are mini populations and therefore are heterogeneous. Selection of one or a few clusters at random to represent the population.
