The study aims at investigating individual performance of
trainees who are subjected to two interrelated courses,
namely, CAD and CADCAM. First, a three factor design
experiment has been conducted to measure the effects of
trainer (A, B), trainee secondary certificate (Scientific
and Industrial) and trainee college esteem (High, Low) on
the mean score of CAD and CADCAM obtained by the population
of trainees graduating in 2006 through 2008. Altogether,
eight combinations having each eight subjects (trainees)
have been considered. The second part of the study carried
out investigation of 25 trainee's scores gained in CAD and
CADCAM training courses by means of a 4-plot exploratory
data analysis (EDA) technique. The following regression
models which deal with the correlation between Exam and
Continuing Assessment scores are established and individual
performances of trainees are outlined.
Key words: ANOVA, regression model, normal distribution,
hypothesis testing, EDA, CAD/CAM. |
