Double-Entry Expectancy Tables.
Wesman, Alexander G.
Test Service Bulletin, n56 p1-9 May 1966
Double-entry expectancy tables are used to make admissions, guidance, or employment decisions based on two predictors. Examples of their use in showing relationships between high school and college performance are explained. The advantages of double-entry expectacy tables given are: (1) relative simplicity of preparation requiring no formal statistical training; (2) ease in understanding; and (3) simultaneous display of relationships among two predictors and a criterion. Questions concerning the construction and use of these tables are answered. Directions are given for constructing a double-entry expectancy table: (1) decide what groupings are to be used for scores on each of the predictors and for scores, ranks or ratings on each criterion; and draw the appropriate grid; (2) make a tally mark for each person in the proper cell for his test scores and criterion rating; (3) when all cases have been tallied, add the number of tallies in each cell and record the sum in that cell; (4) to the right of each row, record the total of the entries in that row; (5) below each column, record the total for that column, using separate totals for each criterion category; and (6) compute percents to answer the various questions one may ask.
