HSS.IC.B.4: Use data from a sample survey to estimate a population mean or proportion; develop a margin of error through the use of simulation models for random sampling.
What you'll learn
- Use a sample statistic (x-bar or p-hat) as a point estimate of the corresponding population parameter (mu or p)
- Use a simulation model for random sampling to generate the sampling distribution of an estimate
- Estimate a margin of error from the spread of the simulated sampling distribution (about two standard deviations)
- Report and interpret an interval estimate (point estimate plus-or-minus margin of error) in the context of the data
- Explain how sample size affects the margin of error, and the meaning and limits of a margin-of-error statement
