Flashcards about Probability Sampling

What is Probability Sampling?

A sampling technique that gives every element (member) of the population an equal chance of being selected as a sample member.

What is Non-Probability Sampling?

A sampling technique that does not give every element or member of the population an equal chance to be selected as a sample because the actual population size is unknown.

What is Simple Random Sampling?

A method of sampling that gives each individual or unit in the entire population an equal chance to be selected.

What is Proportionate Stratified Random Sampling?

A sampling method used when the population has non-homogeneous members and is proportionally stratified.

What is Disproportionate Stratified Random Sampling?

A sampling method used to determine the number of samples when the population is stratified but less proportional.

What is Area (Cluster) Sampling?

A sampling method used to determine samples on very broad objects or data sources, such as the population of a country, province, or district.

What is Systematic Sampling?

A sampling technique that determines samples based on the sequence of population members that have been numbered.

What is Quota Sampling?

A technique for determining samples from a population with specific characteristics up to the required amount.

What is Accidental Sampling?

A sampling technique based on chance encounters where whoever the researcher happens to meet is considered a sample.

What is Purposive Sampling?

A sampling technique for specific purposes only, such as selecting experts in student affairs when researching student discipline

What is Saturated Sampling?

A sampling technique where all members of the population are used as samples, typically done when the population is small.

What is Snowball Sampling?

A sampling technique where the initial sample is small, and then these samples are asked to select their friends to become samples, and so on.

What is Quantitative Data?

Data that is numerical. These data can be in the form of numbers such as 1, 2, 3, and 4.

What is Qualitative Data?

Data expressed in the form of sentences or descriptions, used to explain a problem descriptively.

What is Primary Data?

Data obtained directly from respondents or objects being studied, related to what is being researched.

What is Secondary Data?
