When data leans so hard it needs a wall to stand up straight.
means To make something slant, veer off straight, or distort a result in one particular direction.
from From Old French 'eschuer/eskiuer,' meaning to escape or avoid, which traces back to Germanic roots related to 'shy' — the idea of dodging sideways rather than facing something head-on. Over time 'skew' settled into English as a word for slanting or oblique movement, long before statisticians borrowed it to describe lopsided distributions.
