Sig fig or decimal places for variance?

[ZedCar]

Homework Statement

Calculate variance of 34.1, 35.6, 35.8, 34.3, 32.9, 33.7

Homework Equations

The Attempt at a Solution

A set of numbers: 34.1, 35.6, 35.8, 34.3, 32.9, 33.7

I have calculated the variance to be = 0.208

Would it be better to quote to three sig fig as I have done. This being the number of sig fig of the numbers in the set.

Or should I quote it as 0.2, this being the same number of decimal places of the numbers in the set.

Thanks

here's a reference to help:

from it I'd conclude that 0.208 is the better answer.
