Stem & Leaf Plot

Stem and leaf plots display data distribution in a text-based format that preserves actual data values. Each value is split into a stem (leading digits) and leaf (trailing digit), creating a hybrid of a histogram and a data listing that's useful for small to medium datasets.

"Create a stem-and-leaf plot showing 'Final Exam Scores' for a statistics class of 35 students. Generate realistic grade data with a slight negative skew (most students passing): scores ranging from 52 to 98, mean ~78, median ~80. Stem represents tens digit (5-9), leaves are units digits. Order leaves from lowest to highest within each stem. Include a key showing '7|5 = 75'. Add summary statistics below: n=35, min=52, Q1=72, median=80, Q3=86, max=98, mean=77.8, SD=11.2. Mark the passing grade (70) with an annotation. Highlight the mode(s). Compare distribution shape to normal. Title: 'Statistics 101 Final Exam Score Distribution'."
