# AA.DSR.2: Descriptive & Inferential Statistics

Communicate descriptive and inferential statistics by collecting, critiquing, analyzing, and interpreting real-world data.

- Subject: Mathematics
- Appears in: High School, https://georgiahomeroom.org/standards/math/high-school.md

## Expectations

- **AA.DSR.2.1**: Recognize the purposes of and differences among sample surveys, experiments, and observational studies; explain how randomization relates to each. Distinguish between primary and secondary data and how it affects the types of conclusions that can be drawn.
- **AA.DSR.2.2**: When collecting and considering data, critically evaluate ethics, privacy, potential bias, and confounding variables along with their implications for interpretation in answering a statistical investigative question. Implement strategies for organizing and preparing big data sets.
- **AA.DSR.2.3**: Distinguish between population distributions, sample data distributions, and sampling distributions. Use sample statistics to make inferences about population parameters based on a random sample from that population and to communicate conclusions using appropriate statistical language.
- **AA.DSR.2.4**: Calculate and interpret z-scores as a measure of relative standing and as a method of standardizing units.
- **AA.DSR.2.5**: Given a normally distributed population, estimate percentages using the Empirical Rule, z-scores, and technology.
- **AA.DSR.2.6**: Model sample-to-sample variability in sampling distributions of a statistic using simulations taken from a given population.
- **AA.DSR.2.7**: Given a margin of error, develop and compare confidence intervals of different models to make conclusions about reliability.
- **AA.DSR.2.8**: Summarize and evaluate reports based on data for appropriateness of study design, analysis methods, and statistical measures used.
