Research Questions & Hypotheses 0 What relationship exists between surveyed students’ self- reported rating for self-confidence and the students’ GPA? There is no significant correlation between surveyed students’ self-reported rating for self-confidence and the students’ GPA. 0 What relationship exists between surveyed students’ self reported rating for an understanding of others and the students’ GPA? There is no significant correlation between surveyed students’ self reported rating for an understanding of others and the students’ GPA. 0 What relationship exists between surveyed students’ self reported rating for cooperativeness and the students’ GPA? There is no significant correlation between surveyed students’ self reported rating for cooperativeness and the students’ GPA.

Results 0 Multiple linear regression analysis was computed for students’ undergraduate GPAs based on self-ratings for self-confidence, understanding of others and cooperativeness. This analysis did not produce a significant regression equation (R 2 < 0.01). However, it revealed a statistically significant variance explained by self- confidence levels (B = 0.09), with no significant variances explained by understanding of others or cooperativeness. 0 The data was further analyzed by computing a one-way ANOVA comparing college students’ undergraduate GPA by self-rated reports of self-confidence levels. A significant difference was found for different levels of self-confidence ratings (F(8, 39379) = 67.54, p < 0.01). Tukey’s HSD was used to determine the nature of the differences for students’ reporting different levels of self- confidence. The analysis revealed that students reporting the highest level of self-confidence had significantly higher GPAs (M = 4.49, SD =.97) than students reporting the lowest level of self- confidence (M = 3.79, SD = 1.40).

Findings Based on the results of statistical analysis… 0 we accept the following hypotheses: There is no significant correlation between surveyed students’ self reported rating for an understanding of others and the students’ GPA. There is no significant correlation between surveyed students’ self reported rating for cooperativeness and the students’ GPA. 0 we reject the following null hypotheses: There is no significant correlation between surveyed students’ self-reported rating for self-confidence and the students’ GPA. 0 and for this case we accept the alternative hypothesis: There is a significant correlation between surveyed students’ self-reported rating for self-confidence and the students’ GPA.

Implications and Recommendations 0 These results suggest that colleges should accept applicants exhibiting higher levels of self-confidence if it is the school’s goal to enroll students that are likely to be strong academic performers. 0 Further research may be conducted to explore the effect on students’ GPAs resulting from introducing self-confidence boosting programs.
