The typical value for one group, ignoring the small cases.
You want the typical repair cost for the North region, but only for jobs of at least 100 — the quick fixes distort it. Put that average in B11.
Solve it on your own to keep the bonus. Each hint gets one step closer to the formula.
The same formula in the other shapes it takes at work.
The mean is a fair summary only when nothing in the data is extreme.
Take out the two extremes before averaging, the way judging panels do.

This is the grid you start with. Cell references in the task — B6, C2 — point at the row numbers and column letters below.

| 7 | R-06 | North | 160 |
| 8 | R-07 | North | 60 |
| 9 | R-08 | South | 420 |

| 11 | North, 100+ |
A condition can test the same column you are averaging — here it screens out the small jobs before they reach the average. Like SUMIFS and unlike AVERAGEIF, the range to average comes first.
