Summary
This document details calculations of variances for multiple data sets relating to scores and the reference point "CE." It shows absolute scores, the difference between scores and CE, and the squared differences. The summary of calculations provides a breakdown of the steps involved in these calculations.

This document appears to be about calculating the average variance of a set of scores from a reference point (CE).
