Data can be collected through primary methods, such as surveys and experiments conducted by the researcher, or through secondary methods, where existing data from other sources is repurposed. The quality of statistical analysis is directly tied to the quality of the data sources used. Therefore, careful selection and evaluation of tilastotietolähteet are fundamental steps in any statistical endeavor. Understanding the metadata, or information about the data, such as definitions of variables and collection periods, is also essential for correct interpretation.
