Abstract
The Predicative Validity of the High School Percentage (HSP) to Predict Undergraduate Saudis Student Performance: A Meta-Analysis Study. The purpose of this study was to analyze and examine the predictive validity of students’ high school percentages (HSP) to predict undergraduate grade point average (GPA) as the cognitive predictor of undergraduate students’ academic performance in Saudi Arabia. The researcher reviewed all of the available studies that were conducted on HSP as a predictor of GPA by the use of Meta-Analysis to determine the mean effect size of HSP and determine the power of predictive validity. This researcher reviewed 19 studies, which were conducted on the use of the HSP to predict GPA. All of these studies were conducted in Saudi Arabia during a 30 year period of time from 1981-2011. The total sample for the 19 was 28,185 undergraduate students from different disciplines, universities, colleges, and institutions in Saudi Arabia. The findings from the meta-analysis were: (a) the effect size was 0.40, (b) the fixed effect size was 0.42, and (c) the random effect size was (0.40). The correlations for all of studies showed significance between HSP and GPA at the confidence level of 95%. The average correlation for the 19 studies was 0.419. The findings from the meta-analysis showed that there were no effects of moderator variables for location, major, and years of graduation in the relationship between independent variable and HSP and the dependent variable undergraduate cumulative GPA.
