The Accountant Scale of the Strong Interest Blank for Men bears little direct relation to a criterion of freshman engineering grades. However, it may act as a suppressor variable in conjunction with the Banker or Psychologist Scale of the Strong. It may also aot as a moderator variable in conjunction with the Math.‐Science Teacher or Real Estate Salesman Scale. These effects are illustrated by results obtained in two engineering schools. The basic algebra and geometry of moderator variables is given.
