Data Set Instructions: The 7864 Data Set Is Fictional
Data Set Instructions The 7864 Data Set Is Fictional Data
The data set is a fictional collection representing a teacher's recording of student demographics and academic performance across three course sections with about 35 students each, totaling 105 students. The dataset includes 21 variables capturing demographic information, academic metrics, and performance indicators, stored in a file named grades.jasp, which can be downloaded from the course instructions area and opened in JASP software.
This assignment involves analyzing the dataset to explore relationships among variables, test assumptions, and interpret the results. The analysis plan includes descriptive statistics, testing assumptions such as skewness and kurtosis, conducting correlation analyses, and drawing conclusions based on statistical significance. The final report must present the interpretation of findings in a clear, scholarly manner, aligned with APA guidelines, including sections for assumptions testing, results, discussion, application, and references.

Introduction
The purpose of this analysis is to explore the relationships between students' quiz performances, overall GPA, and final course scores within a fictional dataset representing three course sections. Analyzing such data helps educators understand the predictive power of various assessments on final outcomes, identify potential correlations among different performance measures, and evaluate the assumptions underlying parametric correlation tests. This report discusses the statistical procedures employed, the results obtained, and their implications for educational assessment practices.
Testing Assumptions
Prior to conducting correlation analyses, it is essential to test the assumptions underpinning parametric tests such as Pearson's correlation coefficient. The key assumptions include linearity, normality, and homoscedasticity. For this purpose, skewness and kurtosis statistics for variables—quiz1, gpa, total, and final—were examined to assess normality.
The skewness values ranged from -0.341 for quiz1 to a minimal degree indicating near-normal symmetry, with standard errors of skewness approximating 0.236. Kurtosis values hovered close to zero, with a maximum of 0.277, implying that the distributions do not significantly deviate from a normal distribution. These findings suggest that the data meet the normality assumption reasonably well.
Descriptive Statistics and Correlation Results
The descriptive and inferential statistics reveal noteworthy relationships among the variables. Notably, quiz1 scores correlated strongly with the total points earned (r = 0.797, p
GPA demonstrated a moderate correlation with total points earned (r = 0.318, p
Results Interpretation
The statistically significant correlations support the hypothesis that students' quiz performance, particularly Quiz 1, is positively associated with overall course success markers. The correlations involving GPA, while moderate, indicate that prior academic achievement aligns with performance on assessments and final grades. These findings underscore the importance of early assessments as predictors of final course outcomes, affirming the value of formative assessments in educational settings.
Application
Practical implications of this analysis highlight the utility of early quizzes as indicators for identifying students who may need additional academic support. Educators can leverage such predictors to tailor intervention strategies, improve student engagement, and foster academic success. Furthermore, understanding the strength of these relationships can inform curriculum design, emphasizing assessments that reliably predict final outcomes.
Conclusion
This analysis demonstrates substantive correlations among student assessments, GPA, and final course performance, validating the use of Pearson’s r in educational data analysis. The results advocate for the inclusion of early formative assessments to monitor student progress and guide instructional strategies. Future research could explore additional variables such as demographic factors to deepen understanding of predictive influences on academic achievement.
