Sample statistics and margin of error SAT practice questions
Math, Problem Solving and Data Analysis. 57 questions
What a random sample says about a population, and what a margin of error does and does not mean.
What this skill tests
- Generalizing from a random sample
- Interpreting a margin of error
- Effect of sample size
How to approach it
- 1Results only generalize to the population the sample was drawn from.
- 2A larger sample gives a smaller margin of error.
- 3The margin of error gives a plausible range, not a guarantee.
