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.

A database is an organized collection of data that allows for efficient storage, retrieval, and management of information. It supports various operations such as querying, updating, and maintaining data integrity to facilitate decision-making and application functionality.

A sample is a subset of a population used to represent the whole in statistical analysis, allowing researchers to make inferences about the population without examining every individual. The quality and reliability of conclusions drawn from a sample depend on its size and how well it is selected to reflect the population's diversity and characteristics.

Population refers to the total number of individuals of a particular species living in a specific area, and it is influenced by factors such as birth rates, death rates, immigration, and emigration. Understanding population dynamics is crucial for addressing challenges like resource allocation, environmental impact, and urban planning.

probability of selection

Sampling bias occurs when certain members of a population are systematically more likely to be included in a sample than others, leading to a sample that is not representative of the population. This can result in skewed data and inaccurate conclusions, affecting the validity and reliability of research findings.

representativeness of the sample

Research findings are the results or outcomes derived from systematically conducted studies, providing evidence that either supports or refutes a hypothesis. They are crucial for advancing knowledge, informing policy, and guiding future research directions across various academic and professional fields.
