When stratification is omitted in an evaluation, does it constitute an error?

Omitting stratification in an evaluation does not inherently constitute an error because the necessity of stratification can vary based on the context of the evaluation. Stratification involves breaking down data or evaluations into subgroups to better understand trends, performance, or characteristics within different categories.

In some cases, such as when conducting a general assessment or an evaluation that does not aim to analyze disparities among different groups, omitting stratification might not impact the overall efficacy of the evaluation. Therefore, it is not an error unless the specific purpose of the evaluation necessitates the use of stratified data to yield accurate findings or conclusions.

For instance, if the evaluation is designed to assess overall employee performance without necessarily needing subgroup analysis, the absence of stratification would not affect the validity of the results. Stratification becomes critical when there is a need to highlight variances that could influence decisions like promotions or development needs through a detailed analysis of different demographics within the workforce. However, the question indicates that not including stratification in these cases does not always make it an error.
