問題一覧

is a sample in which every unit in the population has a chance (greater than zero) of being selected in the sample, and his probability can be accurately determined.

Probability Sampling

in a ___ of given size, all such subsets of the frame are given an equal probability. Furthermore, any given pair of elements has the same chance of selection as any other such pair. This minimizes bias and simplifies analysis of results

Simple random sampling

also known as interval sampling, relies on arranging the study population according to some ordering scheme and then selecting elements at regular intervals through that ordered list. ____ involves a random start and then proceeds with the selection of every kth element from then onwards.

Systematic Sampling

a type of sampling method in which the total population is divided into smaller groups or ___ to complete the sampling process. The ___ is formed based on some common characteristics in the population data. After dividing the population into strata, the researcher randomly selects the sample proportionally

Stratified sampling

a probability sampling technique where researchers divide the population into multiple groups ____ for research. Researchers then select random groups with a simple random or systematic random sampling technique for data collection and data analysis.

Cluster sampling

any sampling method where some elements of the population have no chance of selection or where the probability of selection can't be accurately determined. It involves the selection of elements based on assumptions regarding the population of interest, which forms the criteria for selection

Non-probability Sampling

the population is first segmented into mutually exclusive sub-groups, just as in stratified sampling. Then judgement is used to select the subjects or units from each segment based on a specified proportion. In ____ the selection of the sample is non-random.

Quota Sampling

a type of non-probability sampling which involves the sample being drawn from that part of the population which is close to hand. That is, a population is selected because it is readily available and convenient.

Convenience sampling

a sampling technique in which researcher relies on his or her own judgment when choosing members of population to participate in the study

Purposive sampling

appropriate when we want to allow units or cases, whether individuals or organizations, to choose to take part in research on their own accord. The key component is that research subjects (or organizations) volunteer to take part in the research rather than being approached by the researcher directly.

Self-selection sampling

_____ is a non-probability sampling technique where existing study subjects recruit future subjects from among their acquaintances.

Snowball sampling

intended to determine which proportion of a worker's time is devoted to work-related activities

Job Sampling Technique

the process of making sufficient random observations of an operator’s activities to determine the relative amount of time the operator spends on the various activities associated with the job.

Work Sampling

a method of finding the percentage occurrence of a certain activity by statistical sampling and random observations.
