APPENDIX G
Demographic Data
Table G.1 shows part A of the demographic data collected from the Demographic Data Sheet (Appendix A). The column labeled Group specifies to which group a subject belongs. A letter C represents the Control group, and a letter E represents the Experimental group. The column labeled Major specifies the program major that the subject pursues in his studies.
Table G.2 shows the majors and their descriptions. The column labeled level specifies the subject's level of study. The letter U represents undergraduate and the letter G represents graduate. The column labeled Class specifies the class (course) that a given subject was enrolled. CS131 represents the course Programming and Data Structures. CS148 represents the course Theory of Translators. Within the column labeled Sex, the letters F and M represents Female and Male, repectively.
Tables G.4, G.5 and G.6 show the experimental data that was collected from the Subject Performance Evaluation Sheet (Appendix D) for programs Pgm1, Pgm2 and Pgm3, respectively.
