Table

Metric	Near-miss	Far-miss	Handles distance?
Macro-F1	0.605	0.607	No
MAE	0.40	0.80	Yes
QWK	0.894	0.565	Yes

Quote

A metric that cannot tell a near-miss from a catastrophe is not measuring what you think it measures.

Math

Inline math $QWK = 1 - \frac{\sum w_{ij} O_{ij}}{\sum w_{ij} E_{ij}}$ inside a paragraph, and a display block:

$\text{MAE} = \frac{1}{n}\sum_{i=1}^{n}|y_i - \hat{y}_i|$
