Figure 4.
Annual rainfall amounts (June-September)
over the ten years were similar at the two sites:
A paired t-test shows no significant difference
in rainfall amount between the two sites (p = 0.82,n = 9).
The oversampling of annual precipitation amount
therefore appears to occur during the winter
and not during the summer.
Please note that June of 1995 was removed from this graph because of large snowfall events.
