Description: Observed variables are those that can be directly measured in a study, providing concrete and quantifiable data about a phenomenon or a set of phenomena. These variables are fundamental in statistical research, as they allow researchers to collect precise and objective information. Unlike latent variables, which cannot be directly measured and require inferences, observed variables are tangible and obtained through data collection methods such as surveys, experiments, or records. Their measurement can be qualitative or quantitative, depending on the nature of the data collected. Observed variables are essential for statistical analysis, as they form the basis upon which inferences are made, relationships are established, and models are developed. Clarity in the definition and measurement of these variables is crucial to ensure the validity and reliability of the results obtained in any study. In summary, observed variables are a key component in applied statistics, as they enable researchers to transform data into useful and meaningful information.
