Abstract:
Objective: 1. To find relationship between sport practicing time (SPT) and academic achievement (GPAX) 2. To investigate relationship between studying time (ST) and GPAX. 3. To establish Chulalongkorn University Athletes in 2012’s GPAX (CUA) predicting model. Method: A cross sectional survey research was performed. All CUA 2012 was the population frame. Probability simple random sampling was executed to collect sample. Sample size was calculated according to Hair et al (2012) n=125, alpha=0.05, The 22 measurement variables were identified. Stern’s modify test (1938, 2010) consisted of 15 items was used to calculate Intellectual concept. Demographic data were also collected. Hierarchical stepwise Multiple Regression Analysis (MRA) was employed to analyze the model. Results: 125 (100%) respondents participated. SPT had negative correlation with GPAX (r=0.07, p=0.75, Pearson’s correlation), ST had negative correlation with GPAX (r=-0.01, p=0.29, Pearson’s correlation). Conclusion: Among 5 factors namely gender, age, ST, SPT and IQ, IQ was only a significant predictor to GPAX. The prediction GPAX equation was 0.77 IQ**+0.02 male-0.05 age+ 0.02 SPT–0.06 ST (p=0.00, R2= 0.59, MRA).
