Vocational Tests for Agricultural Engineers

Abstract

Mental tests were devised for the purpose of predicting ability in agricultural engineering and were standardized upon forty-three students. For interpreting the results of the tests when given for purposes of vocational guidance or selection a ten by ten fold table for the correlation of .60 and its standard error of estimate was derived from the probability integral. Knowing an individual's weighted test score, it is possible with such a table to state the probability of his attaining any assigned degree of ability in agricultural engineering.
