Study Notes
Sampling Methods
- The main purpose of stratified sampling is to divide the population into homogeneous subgroups (strata) to ensure each subgroup is adequately represented.
Systematic Sampling
- Systematic sampling is characterized by selecting every nth individual from a population, where n is a fixed interval.
Cluster Sampling
- The defining feature of cluster sampling is the division of the population into smaller groups or clusters, and then selecting a few clusters to represent the population.
Multi-Stage Sampling
- The primary goal of multi-stage sampling is to select a sample in multiple stages, starting with larger units and gradually moving to smaller units.
Random Sampling
- Random sampling entails selecting participants randomly from a population, ensuring each individual has an equal chance of being selected.
Questionnaires in Social Science Research
- The main objective of using a questionnaire in social science research is to gather self-reported data from participants.
Types of Validity
- Construct validity refers to how well a concept, idea, or behavior is transformed into a functioning reality.
Criterion-Related Validity
- Criterion-related validity measures how well a test or instrument correlates with a criterion, such as a gold standard or a future outcome.
Establishing Reliability
- The aim of using the test-retest or stability test method is to establish reliability by demonstrating that the instrument yields consistent results over time.
Instrument Sensitivity
- An instrument demonstrates sensitivity if it is able to detect subtle changes or differences in the variables being measured.

Description
This quiz covers the process of determining the locale of the study and selecting respondents or participants for a research study. It includes the elements of location, total population, and types of sampling designs such as probability and non-probability, with a focus on (simple) random sampling.
