M303 Final - Nonprobability Sampling Techniques

Front 1

with non probability sampling techniques, sampling units are selected on basis of __________ or ________ so the probability of any particular population element being chosen for the sample is unknown

Back 1

convenience

judgment

Front 2

sample consists of the most conveniently available (easy to reach) population elements

researcher selects population elements who are in the right place at the right time

Back 2

convenience sampling

Front 3

form of convenience sample; researcher uses personal judgment about some appropriate attribute of the population element to select the sample

researcher uses his/her judgment and experience to select population elements for the sample

Back 3

judgment (purposive) sampling

Front 4

researcher ensures that population subgroups are represented in the sample on relevant characteristics by establishing quantity targets for each subgroup

(making sure part time and full time students are represented in a survey)

Back 4

quota sampling

Front 5

3 steps of quota sampling

Back 5

1. researcher uses judgment to identify population subsets

2. set quotas for each subset in the sample

3. then use a convenience or judgment sampling technique to select population elements

Front 6

used for a target population with population elements that are difficult to identify/locate

researcher selects the initial population elements through a probability sampling method with more population elements (potential respondents) located using contact info provided by the initial respondents

Back 6

snowball/referral sampling
