Below shows the distribution of values for the scores for the different assignments:
The below boxplot illustrates the distribution of the Formative Assessment scores grouped by the final letter grade. It shows that, in general, how students perform in the formative assessment tends to be similar to how they would perform in the final assessment. There are also some outliers, such as students with A- performing worse in the final assessment, and students with B- performing significantly better in the final assessment.
The relationship between formative assessment and final grades shows a positive trend in the below scatterplot, meaning that as the formative assessment score increases, the final grade also tends to increase.
The correlation coefficient between students' formative assessment scores and the final grades is also high (0.534), as shown in the below table. To predict students' final assessment score, the equation would be 63.89 + (0.53*formative-assigments-score).
