THIS SELF-INSTRUCTIONAL PROGRAM PROVIDES INFORMATION ON BEHAVIOR EVALUATION AND GRAPHING AND RELATED CALCULATIONS IN ILLUSTRATED NARRATIVE FORM; FILL-IN QUESTIONS AND MATHEMATICAL PROBLEMSOLVING ARE INCLUDED THROUGHOUT, WITH ANSWERS PROVIDED. IT IS INTENDED THAT THE USER START AT THE BEGINNING OF THE BOOKLET, WORK STRAIGHT THROUGH, WRITE ANSWERS AND SOLVE PROBLEMS AS DIRECTED, AND CHECK COMPLETED WORK. IN ORDER TO EVALUATE CORRECTIONAL PLAN EFFECTIVENESS, COUNTING OR ESTIMATING BEHAVIOR BEFORE, DURING, AND AFTER PLAN IMPLEMENTATION AND PLOTTING RESULTS ON A GRAPH MAY BE USEFUL. THE TIME SAMPLE METHOD SHOULD BE EMPLOYED WHEN THE CORRECTIONAL OFFICER IS NOT AVAILABLE TO COUNT EACH BEHAVIOR; USING THIS METHOD, THE OFFICER CHECKS IN ON THE INMATE AT DIFFERENT TIMES DURING THE DAY AND RECORDS THE NUMBER OF TIMES THE DESIRED BEHAVIOR IS OBSERVED, AS COMPARED WITH THE NUMBER OF TIMES THE INMATE IS CHECKED. THE TIME SAMPLE METHOD FOR A GROUP TAKES INTO ACCOUNT THE NUMBER OF MEN WHO COULD BE PERFORMING THE BEHAVIOR, WHATEVER THAT NUMBER IS AT ANY TIME. THE GROUP TIME SAMPLE METHOD ALLOWS THE CORRECTIONAL OFFICER TO COMPARE THE WORK DONE BY A SMALL GROUP OF MEN WITH WORK DONE BY A LARGER GROUP. TO COUNT THE BEHAVIOR BY THIS METHOD, THE CORRECTIONAL OFFICER MUST COUNT TWO THINGS EACH TIME THE GROUP IS OBSERVED, THE NUMBER OF MEN PERFORMING THE BEHAVIOR AND THE TOTAL NUMBER OF MEN WHO COULD BE PERFORMING THE BEHAVIOR. TO GET THE DAILY PERCENT PER MAN FOR A GROUP, THE NUMBER OF BEHAVIORS (NUMBER OF MEN PERFORMING BEHAVIOR) IS DIVIDED BY THE NUMBER OF TIMES THE CORRECTIONAL OFFICER LOOKS AT EACH MAN (TOTAL NUMBER OF MEN IN GROUP). THIS DAILY PERCENT PER MAN IS THE AVERAGE TIME THAT EACH MAN IN THE GROUP IS PERFORMING THE DESIRED BEHAVIOR. SKETCHES, GRAPHS, AND SAMPLE PROBLEMS ILLUSTRATE THE TEXT. (LWM)
