Manual data setup Line plot by student Histogram with PDF overlay Levene’s test QQ plot + Shapiro-Wilk test Box plot per module Summary of group and overall means

his report visualizes the number of submission attempts made by five students (including myself) for the Module 2 R Markdown assignment on estimating the mean. I used a histogram with a normal probability density function (PDF) overlay to illustrate the distribution of our submission counts. The plot includes: A histogram of individual submission values A normal curve based on the sample mean and standard deviation Labeled points showing each student’s name and submission count A summary box in the upper left corner with the calculated mean, variance, and standard deviation While the sample size is small, the goal was to apply the concepts we practiced in Module 2 (like visualizing distributions and calculating basic statistics) using real data from the class. This analysis was created as part of an optional Yellowdig post to crowdsource and analyze our shared progress.
