Below are sample questions representative of the exercises included on this worksheet and related 7.122 Planning data collection and recognizing bias skill assessments:

Problem 1Difficulty: Mastery

The school wants to estimate the average amount of money students spend at vending machines in a week.

Which plan is least biased?

AAsk only students who are seen buying snacks.

BAsk students to guess how much they spend each week.

CSurvey only athletes after practice.

DRandomly select students and, for that week, have them keep a spending log and compare it with vending machine purchase records when possible.

Solution & Explanation:Random selection helps the sample represent all students, including those who rarely buy snacks. Using a log and records reduces memory errors compared with guessing, and avoids focusing only on athletes or frequent buyers.

Problem 2Difficulty: Mastery

A tech club wants to compare battery life of Phone Model A and Phone Model B for typical daily use.

Which plan is least biased?

AAsk people online which phone they think has better battery life.

BCompare one student's Model A that is 2 years old to a new Model B.

CSet both models to the same settings, run the same apps in the same order, and time how long each lasts; repeat with several phones of each model.

DUse only battery life claims from advertisements.

Solution & Explanation:A controlled test with the same settings and tasks isolates the phone model as the main difference. Repeating with several phones reduces the chance that one unusual device changes the result.

Problem 3Difficulty: Mastery

A city wants to know the typical monthly cost of housing for residents. The city surveys only property owners using the property tax list.

What is the main bias problem?

ACosts change each month.

BRenters are excluded from the sample, so the results may not represent all residents.

CThe survey uses a list.

DHousing costs are dollars.

Solution & Explanation:The property tax list includes owners but not renters. If renters pay different amounts than owners, excluding them causes undercoverage and biases the estimate for all residents.
