The Weibull plotting method is commonly used in flood-frequency analysis.
The basic procedure invovles ranking the values from highest to lowest and
calculating an exceedence probability (*p = rank / (n + 1)*) where n
is the total number of observations. The median annual flood (Q2) is the
flow with a probability of 0.5.
