Sampling Techniques Flashcards
- entire set, actual or conceptual of subjects in a survey or study
- where satistician wants to draw conclusion
population
systematic process of selecting individuals, unit, or groups
sampling
what is one way to determine the sample size of your study?
n=N/(1+Ne^2)
Slovin’s formula
refers to a sampling technique in which samples are obtained using some objective chance mechanism, thus involving randomization
Probability
You assure every member the same chance/opportunity
to be in the sample.
Simple Random
It requires a list of the elements and every nth element in the list is drawn for inclusion in the sample.
Systematic Random
This process selects samples in the same proportion from the different subgroups of strata.
Stratified Random
It is used when the target respondents in a research
study is spread across a geographical location. In this
method, the population is divided into groups called
clusters.
Cluster Random
It involves non-random selection based on convenience or criteria, allowing you to easily collect data.
Non-Probability
The researchers decides on criteria and the criteria should meet the needs of the study.
Purposive Sampling
Participants are selected based on availability and willingness to take part.
Convenience Sampling
It gathers a representative sample from a group based on certain characteristics of a population chosen by the researcher.
Quota Sampling
It is a technique where a researcher identifies a key
informant about a research of interest and then ask the
respondent to refer or identify another respondent who can participate in the study.
Snowball Sampling
This way to determine the sample size uses a standard number of sample size
Heuristic approach
According to heuristic approach, how many number of participants must be in a research design, survey?
800
