Study Notes
Sampling Fundamentals
- Sampling is the process of selecting a subset of individuals or data points from a larger population to make inferences about the population as a whole.
Key Definitions
- A sample is a subset of individuals or data points selected from a larger population to represent the population.
- A sampling frame is the list of all individuals or data points in the population from which the sample is drawn.
Sampling Methods
- Convenience sampling is a non-probability sampling method where participants are selected based on their availability, proximity, or ease of access, often leading to a biased sample.
- A simple random sample is a probability sampling method where every individual or data point in the population has an equal chance of being selected, resulting in a representative sample.
Test your knowledge on sampling techniques and learn about the process of selecting a representative sample from a population. Explore the concepts of population and sample, and understand how to generalize study results to the larger population.
