The total number of quakes above magnitude 2 that occurred during the 3 days in the marked area was 22, 21% more than usually. This is compared to the average number (Ø) of 18.2 quakes obtained from the 100 preceding 3 days intervals with a standard mean deviation (σ) of 26.4 (which is a measure of the typical amount of variation, or spread, of quake numbers during such a time interval).
Interpretation: There is no significant variation in the number of quakes that occurred during the past 3 days.
