    ANOVA Analysis and Interpretation

    The Analysis of Variance (ANOVA) serves as a statistical tool to explore the relationship between gender (independent variable) and GPA (dependent variable). Gender is considered a categorical variable, while GPA is treated as a continuous variable. This research endeavor aims to investigate the impact of gender on GPA levels. The null hypothesis posits that gender has no significant effect on GPA levels, while the alternative hypothesis suggests that gender does exert an influence on GPA. The assumptions necessary for this test are outlined in Table 1.

    Independent Samples Test

    Levene’s Test for Equality of Variances

    Levene’s test assesses the equality of variances between GPA (dependent variable) and Gender (independent variable). A significance level below .05 indicates substantial differences in variances. In this study, the data in Table 1 reveals a significance level of .758, suggesting no significant difference between the two variables. Assumptions of equal variances are maintained, indicating homogeneity.

    Results and Interpretation

    Table 2

    Group Statistics

    Table 2 presents group statistics illustrating the mean GPA for females (n=64) at 2.97 with a standard deviation of 0.678 and for males (n=41) at 2.69 with a standard deviation of 0.739. Despite the assumption of equal variances, the homogeneity assumption is not met. The significance value of .048 in Levene’s test indicates slightly different variances. However, as .048 < .05, the null hypothesis is not rejected, and the variability between the groups is not deemed significant.

    Statistical Conclusions

    This study investigates GPA differences among genders using an equal variance t-test, revealing a statistically significant difference in GPA means for males and females (Males: M = 2.69, SD = 0.74; Females: M = 2.97, SD = 0.68, p = .758 > .05). Limitations include assumptions associated with the t-test and unequal sample sizes. Future studies could delve into support networks for achieving higher GPAs.

    Application

    Proficient HR leaders can employ trend analysis tools, such as time and attendance, to identify factors influencing staff outcomes. For example, staffing initiatives and the effectiveness of safety training can be evaluated. Continuous analysis aids in recognizing factors impacting workplace activities and employee outcomes.
