What is the primary focus when using a stratified analysis in assessment?

The primary focus of using a stratified analysis in assessment is to compare averages. Stratified analysis involves dividing a population into distinct subgroups or strata, which allows for a more nuanced understanding of variations within the data. By comparing the averages of different strata, assessors can identify how various factors like property types, locations, or market segments perform against each other. This method is particularly useful in property assessments as it provides insight into the different characteristics that may influence property values and helps ensure fair assessments.

While other aspects like forecasting trends, risk assessment, or identifying anomalies can be relevant in assessment analysis, the core purpose of stratifying data is primarily to facilitate robust comparisons among defined groups. This targeted approach enhances the accuracy of assessments and helps in maintaining equity in property valuation.
