What does “variance” mean?

variance

Oh, this is a useful one —

"Variance" basically means a difference or change from what you expected or planned. It's when something doesn't match the original idea.

So imagine you think a project will cost $500, but it actually costs $600 — that $100 gap is the variance. You might hear someone at work say, "There's a big variance between our plan and the real results."

It also shows up in math and statistics, where it means how spread out or different numbers are from each other. Like, "The test scores had a high variance" — meaning some students got very high scores and some got very low ones.

And sometimes people say "at variance with" to mean disagreeing with something — like, "His opinion is at variance with mine."

Basically, variance = the gap, difference, or spread between things.
