What type of data does the term 'X or Y' refer to in statistical measurements?

The term 'X or Y' in statistical measurements typically refers to individual measurements or raw scores. This designation highlights distinct data points that represent specific observations or individual cases within a dataset. Such raw scores are the fundamental building blocks of analysis in statistics, as they provide the essential information necessary for further statistical manipulation, analysis, and interpretation.

In contrast, statistical methods refer to the techniques and processes employed to analyze data, while aggregated sample data involves summarizing data points into a collective metric, which depersonalizes individual scores. Comparative observational data emphasizes the comparison between different sets of observations, rather than focusing solely on individual values. Therefore, focusing on individual measurements or raw scores is crucial for understanding the basic elements of statistical data and analysis.
