Measure vs Evaluation example Re: Minutes: Silver meeting of 19 January 2021

Here is an example that is directly related: Visual Contrast.

Measure: Put in two colors into the APCA tool, and it gives a measure of the predicted contrast for those two colors if they are adjacent and touching. The tool also gives a minimum font size and weight.

But here’s the rub: there is no standard for weight or size of fonts.

Evaluation:  So the evaluation is that a font must be compared to the standard (Helvetica or Arial) and adjustments made to compensate for differences. This is somewhat subjective and not a measure, but an evaluation.

A third type that is often part of the above two in some way:

Empirical: A measure may be via a tool that is using a sampling of data collected through evaluation or empirical study, i.e. a consolidation of multiple evaluations or an averaging of multiple measures, usually made by different individuals. Something that is a measure may be based on something that was originally an evaluation, and an evaluation may be based on parameters that were derived from a range of measurements.
