Distribution
7.SP.B.3
Definition
Describes how data values are spread across a range. Described by shape (symmetric, skewed, or uniform), center (mean or median), and spread (range or MAD).
Teach it
Where it is taught, with guided notes, practice, homework, an exit ticket and an interactive Teacher Deck.
Examples
- A roughly symmetric (bell-shaped) distribution with mean ≈ median ≈ 80.
- Right-skewed: tail goes right, most data on the left; left-skewed is the reverse.
Key rule
Always describe a distribution by its shape, center, and spread.
Memory hook
Shape, center, and spread tell the whole story.
