7.SP.A.2

7.SP.A.2 -- Use data from a random sample to draw inferences about a population with an unknown characteristic of interest. Generate multiple samples (or simulated samples) of the same size to gauge the variation in estimates or predictions. For example, estimate the mean word length in a book by randomly sampling words from the book; predict the winner of a school election based on randomly sampled survey data. Gauge how far off the estimate or prediction might be.

What you'll learn

Use data from a random sample to estimate an unknown characteristic of a population
Express an estimate as a proportion or percent and interpret it in the context of the population
Explain that different random samples from the same population will produce different estimates (sampling variability)
Use multiple random samples to gauge the range of plausible estimates for a population characteristic
Distinguish between estimates with high and low variability based on sample size and sampling method
Evaluate the reliability of a population estimate based on the sampling process used

Review first:

Understand that statistics can be used to gain information about a population by examining a sample
