Probability sampling
Involves the random selection of participants from a population, giving each individual an equal chance of being selected
Includes simple , stratified random sampling, and cluster sampling
Allows for the generalization of findings to the larger population and reduces sampling bias
Non-probability sampling
Involves the non-random selection of participants based on specific criteria or convenience
Includes , , and
May be less representative of the population but can be useful for exploratory research or hard-to-reach populations
Sample size considerations
Refers to the number of participants required to achieve statistically significant results and ensure the reliability of findings
Depends on factors such as the research design, population size, and desired level of precision
Larger sample sizes generally increase the precision and generalizability of findings but may be more resource-intensive
Data collection methods
Refers to the techniques used to gather information from participants or sources
Can be broadly categorized into primary data collection (data collected specifically for the research) and secondary data collection (data collected by others for different purposes)
The choice of data collection methods depends on the research question, design, and available resources
Surveys and questionnaires
Involve the use of structured or semi-structured instruments to collect data from a large number of participants
Can be administered through various modes, such as online, mail, or in-person
Examples include opinion polls (political science), consumer surveys (marketing research), and personality inventories (psychology)
Interviews and focus groups
Involve the use of open-ended questions to gather in-depth, qualitative data from participants
Interviews can be conducted one-on-one or in small groups (focus groups) to explore attitudes, beliefs, and experiences
Examples include life history interviews (sociology), expert interviews (policy research), and consumer focus groups (market research)
Observational techniques
Involve the systematic recording of behavior or phenomena in natural or controlled settings
Can be conducted using structured observation schedules or unstructured, ethnographic approaches
Examples include classroom observations (education research), wildlife observations (ecology), and participant observations (anthropology)
Secondary data sources
Involve the use of existing data collected by others, such as government statistics, archival records, or previous research studies
