Coverage error occurs when the sampling frame does not adequately represent the target population, leading to biased results. It is a critical issue in survey research that can compromise the validity of findings if certain groups are systematically excluded or underrepresented.

Coverage Error

Coverage error

A sampling frame is a comprehensive list or database from which a sample is drawn for a study, ensuring that every member of the population has a known probability of selection. It is crucial for minimizing sampling bias and enhancing the representativeness of the sample in research findings.

sampling frame

The target population is the specific group of individuals or entities that a research study, survey, or intervention aims to understand, assess, or affect. Clearly defining the target population is crucial for ensuring the validity and applicability of the study's findings, as it influences the sampling strategy and the generalizability of the results.

Survey research is a method of collecting data from a predefined group of respondents to gain information and insights on various topics of interest. It is widely used across disciplines for its ability to gather large amounts of data efficiently and its flexibility in terms of question design and administration modes.
