lähdepopulaation

Lähdepopulaation, also known as source population, refers to the original group of individuals from which a sample is drawn in statistical studies. This term is crucial in the field of statistics and research methodology, as it defines the scope and characteristics of the population that is being studied. The source population is distinct from the target population, which is the group of individuals or entities that the researcher is ultimately interested in studying. The source population is often larger and more accessible, making it a practical choice for sampling. However, it is important to ensure that the source population is representative of the target population to maintain the validity and reliability of the study's findings. Properly defining and understanding the source population is essential for designing an effective sampling strategy and drawing accurate conclusions from the data collected.
