Sampling Technique Flashcards
Every person in the population has an equal chance to be part of the sample
Simple Random Sampling
There is a gap or sample interval (e.g., every 5th person) between each selected subject in the sample after randomly selecting a starting point.
Systematic Sampling
Population is divided into homogenous, mutually exclusive subgroups (strata) and a sample is selected from each strata
stratified sampling
Used when population is scattered across a large geographic area; divided the population into are blocks (cluster) and randomly select from these clusters
Cluster Sampling
Using a more combination of two or more probability sampling methods in different stages; involves selecting a sample in at least 2 stages
Multi-Stage Sampling
Every person in the population has an equal chance to be part of the sample
Simple Random Sampling
There is a gap or sample interval (e.g., every 5th person) between each selected subject in the sample after randomly selecting a starting point
Systematic Sampling
Population is divided into homogenous, mutually exclusive subgroups (strata) and a sample is selected from each strata.
Stratified Sampling
Used when the population is scattered across a large geographic area; divided the population into are blocks (clusters) and randomly selected from these clusters
Cluster Sampling
Using a combination of tow or more probability sampling methods in a different stages; involves selecting a sample at least two stages
Multi-Stage Sampling
Subjects are selected according to who is available or can be accessed conveniently. Any subject may be included in the sample
Convenience Sampling
After data is gathered from selected subject, the researchers asks them in the whereabouts of other potential subjects to be included in the sample
Snowball Sampling
Subjects are selected according to a set criteria with a definite purpose in mind. Researchers assume that some subjects are better fit than others depending on the purpose
Purposive Sampling
Selecting a set number of participants out of subgroups based on specific requirement or predefined category
Quota Sampling
