What is "Inference from sample statistics and margin of error" on the Digital SAT?

It is an official College Board skill in Digital SAT Math. The wording on Bluebook matches the domain taxonomy Drilled uses in drills, analytics, and the notebook.

How does Drilled train Inference from sample statistics and margin of error?

Filter the bank to the skill, run a timed drill, autopsy every miss, and let the notebook bring the same pattern back. Domain drills and full section sims include the skill at the official mix.

Inference from sample statistics and margin of error

Margin of error is a language test wearing a statistics costume. The interval is estimate ± ME. What you are allowed to claim is the whole question.

What Bluebook is testing

Q.F. is inference from sample statistics and margin of error. Larger samples, smaller ME. The interval is not a guarantee about every individual.

How it shows up

A poll result plus an ME, then four claims. Three overclaim. One stays inside the interval and talks about the population parameter, not a person.

A method that survives Module 2

Build the interval first: statistic ± ME. Any claim outside it is dead. The interval is about the population value, not about one person in the sample. If n changes and they ask what happens to ME, direction is enough — you rarely need the formula.

Traps that look like knowledge

Saying the interval contains every individual value
Treating ME as a standard deviation of the data
Ignoring that a larger sample should shrink the ME
Claiming a cause from a sample statistic
