Abstract

A t-test is given to test monthly temperature normals, and a new test related to the F-test is developed for testing monthly precipitation normals. The theory involving the two errors committed in using such tests is discussed. This theory is used to set the probabilities of type 1 and 2 errors at predetermined levels. The tests are applied to examples from the normals revision program.
