Reliability and validity are two key problems in the analysis of existing statistics. Reliability refers to the consistency and repeatability of the measurement, while validity refers to the accuracy and relevance of the measurement in relation to the concept being studied. These two issues are crucial in ensuring the credibility and usefulness of statistical data. Sampling size and sampling error, longitudinal and cross-sectional issues, units of analysis and the ecological fallacy, and subjectivity and sampling error are all important considerations in statistical analysis, but they do not represent the two key problems in the way that reliability and validity do.
