The difference

What the test and control actually produced.

The part

What it is

In absolute terms and as a percentage, since a large relative difference on small volumes is not evidence.

Reported for the whole period rather than for the best sub-period within it.

The smallest level

The attributes it carries

Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
