Margin of error and what a sample supports
Interpret sampling variability margin of error and supported claims
Problem types
- Interpret a margin of error
- Estimate a population mean
Builds on
- Studies, experiments, and samples
- Comparing two data distributions
- The normal distribution · Earlier idea
Means of repeated samples vary in a roughly normal pattern, so the same rule that gives percents within standard deviations gives the margin of error.
- A distribution built from frequencies · Earlier idea
The distribution of many simulated sample statistics estimates the sampling variability used in statistical inference.
- A distribution from a sample space · Earlier idea
A theoretical distribution of sample means gives the margin of error used in statistical inference.
