Data analysis is a crucial process that helps teachers to gain valuable insights into the performance of their students on a graded assignment. The detailed report generated through data analysis provides a wide range of information to teachers. One of the key benefits of this report is that it allows teachers to understand the percentile range that the majority of their students fall under using a normal distribution graph. This information is particularly useful in evaluating the effectiveness of the assignment and identifying areas where students may be struggling.

In addition to this, the detailed report provides a breakdown of each question in the assignment. This breakdown reveals which questions students have performed poorly in terms of their responses. Teachers can use this information to identify the specific topics or concepts that students are struggling with and adjust their teaching accordingly. The report can show up to 10 questions where students have performed poorly, providing a clear picture of the areas that need improvement.
