Build frequency, relative-frequency, and cumulative-frequency tables from bins.
Theory
Build frequency, relative-frequency, and cumulative-frequency tables from bins. This lesson treats charts as analytical tools. Students focus on the data question, variable type, source, scale, and audience before choosing or interpreting a display.
Explanation 1
Use clear titles, labels, and units.
Explanation 2
Keep source and scale choices visible.
Explanation 3
Interpret patterns cautiously and avoid decorative chart junk.
Interactive Mission
Different bins can tell different stories. Compare the shape before interpreting.
R connection
Run and edit the R code. Use the floating guide for line-by-line explanations and common beginner mistakes.
Live R Lab

Reflection
Name the data question, the display, and one limitation.
Assistant
Coach me on Frequency Distributions without giving direct quiz answers. Ask me to justify chart choice, scale, and interpretation.
