Depends on whether you want to know the error in relation to estimation or to real situation.

Explanation:

The difference is #325-300=25#

This is #25/300xx100%~~8.3%# of the estimate, so you can say "attendance was 8.3% above the estimate"

This is also #25/325xx100%~~7.7%# of the outcome, so you can say "the expectation was 7.7% lower than what happened"

Let's say the percent error is "around 8%"....
