a
Multiply and divide the mean variability by this factor to get typically high and low individual values of the variability.
AFL, Australian football league; SD, standard deviation; SEE, standard error of the estimate; CL, confidence limits.
Likelihood: P, possibly; L, likely; VL, very likely; ML, most likely.
Magnitude of variability: ↔ trivial; ↕ small; ↕↕ moderate.
Magnitude of trend: ↔ trivial; ↑ small increase.
