Below are sample questions representative of the exercises included on this worksheet and related 6.112 Write Scientific Explanations and Arguments skill assessments:

Problem 1Difficulty: Mastery

Which procedure best controls variables to test the argument?

ALet participants choose when to meditate and report their own blood pressure readings.

BMeasure blood pressure right after meditation but measure the control group later in the day.

CCompare people who meditate regularly to people who never meditate.

DUse a randomized crossover study where participants complete meditation and a matched quiet-rest placebo on different weeks, keep measurement time and posture constant, and use automated cuffs for blinded readings.

Solution & Explanation:A crossover design controls individual differences, a matched quiet-rest condition controls for taking a break, and consistent automated measurements reduce bias.

Problem 2Difficulty: Mastery

Which procedure best controls variables for a fair comparison?

AMeasure lead with different test kits depending on availability.

BTreat different water sources with different chemicals and compare the results.

CMake one large batch of lead-contaminated water at a known concentration, split it into equal samples, treat with equal doses of each chemical for the same time, then measure lead with the same calibrated instrument with replication.

DUse a higher dose of the new chemical because it is safer to use.

Solution & Explanation:A single starting batch controls initial lead level, equal dosing and time isolate chemical type, and consistent calibration controls measurement error.

Problem 3Difficulty: Mastery

Which procedure best controls variables to test this argument in a school?

AAsk students if the air feels cleaner and use that as evidence.

BInstall the new filter only in the classroom with the highest absences and see if absences drop.

CRandomly assign similar classrooms to receive the new filter or a standard filter, keep attendance reporting identical, measure air particle counts, and compare absences over the same weeks.

DCompare one school that buys the filter to another school that does not.

Solution & Explanation:Random assignment controls classroom differences, measuring air particles supports the mechanism, and identical reporting reduces measurement bias in absence counts.
