What This Stem-and-Leaf Worksheet Covers
A stem-and-leaf plot (or stemplot) displays quantitative data by splitting each data value into a "stem" (the leading digit or digits) and a "leaf" (the final trailing digit). Unlike histograms, stemplots preserve every original data value while still demonstrating overall shape:
Constructing Ordered Stemplots
Aligns with CCSS.MATH.CONTENT.6.SP.B.4. Students extract stems and leaves, arrange leaf values in strict ascending numerical order across rows, and align digits into clean columns.
Creating Keys with Units
Aligns with CCSS.MATH.CONTENT.6.SP.B.5. Students provide an unambiguous key (e.g., Key: 3 | 5 = 35 miles per hour) to establish place value for integer or decimal interpretations.
Back-to-Back Comparisons
Aligns with CCSS.MATH.CONTENT.7.SP.A.3 and High School standards. Students compare two independent groups sharing a central stem column, analyzing differences in medians, spreads, and cluster modality.
Example Question & Worked Solution
Here is an authentic sample question demonstrating stemplot construction and summary calculations:
Problem Context: Typing Speeds (Words per Minute) for 14 Students
Student Task: Construct an ordered stem-and-leaf plot with an accurate key. Then determine the median, mode, and range of the typing speeds.
Worked Solution:
- Median (Middle of 14 numbers): Average of 7th and 8th values: (44 + 46) / 2 = 45 wpm
- Mode: 35 appears twice → Mode = 35 wpm
- Range: 62 - 28 = 34 wpm
- Distribution Shape: Unimodal and approximately symmetric centered in the 40s.
