Grade 6 · Data, Statistics & Probability
Statistical Distributions
Learn to organize, summarize, and interpret information from data through clear explanations, worked examples, an interactive model, and guided practice.
Lesson coverage
Learn the whole topic, not just one problem type.
This lesson and its practice bank deliberately rotate across these core facets so students build a connected understanding of the subject.
Interpret tables, plots, and graphs.
Use mean, median, or another appropriate center.
Reason about variation, clusters, and distributions.
Compare groups or relationships between variables.
Use data to support a conclusion while respecting limitations.
Build the idea
Statistical Distributions is part of the transition into middle-school mathematics through ratios, rational numbers, expressions, equations, geometry, and statistics. Start by identifying what each quantity, symbol, diagram, or graph represents before calculating.
Read representations
Interpret tables, plots, and graphs. Use a representation that fits the idea, connect it to the relevant mathematical relationship, and explain how the representation supports the result.
Center
Use mean, median, or another appropriate center. Use a representation that fits the idea, connect it to the relevant mathematical relationship, and explain how the representation supports the result.
Spread & shape
Reason about variation, clusters, and distributions. Use a representation that fits the idea, connect it to the relevant mathematical relationship, and explain how the representation supports the result.
Compare data
Compare groups or relationships between variables. Use a representation that fits the idea, connect it to the relevant mathematical relationship, and explain how the representation supports the result.
Inference & application
Use data to support a conclusion while respecting limitations. Use a representation that fits the idea, connect it to the relevant mathematical relationship, and explain how the representation supports the result.
Use a reliable strategy
Identify what the data or outcomes represent, choose an appropriate summary or probability model, calculate, then interpret the result in context.
Check and explain
A correct answer is only part of mathematical understanding. Check units, signs, scale, and whether the result makes sense. Then explain the relationship in words so you can recognize the same structure when the numbers or context change.
Key terms
Words to know
- Statistical Distributions
- The central skill or relationship explored in this lesson.
- Data
- Recorded observations or measurements.
- Distribution
- How data values are spread across possible values.
- Center
- A value used to describe the middle of a data set.
Interactive math lab
Change it. See it. Understand it.
Adjust the values and watch the relationship respond.
| Quantity A | 6 |
|---|---|
| Quantity B | 3 |
| Rate / ratio | 2 |
Worked examples
See the idea in action.
Add the values and divide by 3: (3+5+7) ÷ 3 = 5.
A distant value makes the data more spread out.
Guided practice
20 questions drawn from a 150-question lesson bank.
Each practice session mixes the major skills in this lesson so you practice the whole topic, not just one repeated problem type.
Which representation is best for showing how categories compare by count?
