Data Validation

Data validation is the process of ensuring that the information collected is accurate, consistent, and reliable. It involves checking data against predefined criteria or rules to confirm its quality before it's used for analysis or decision-making. For example, in a survey, data validation might involve ensuring that responses fall within expected ranges or formats. Effective data validation helps prevent errors, misinterpretations, and unreliable conclusions, thereby enhancing the overall integrity of the information used in various contexts, such as research, business, and policy-making.
