Below are sample questions representative of the exercises included on this worksheet and related Pre CAL.178 Recognize Bias and Limitations in Data Collection skill assessments:

Problem 1Difficulty: Mastery

Which option correctly identifies the main source of bias and the best improvement to reduce it?

ABias: Survivorship bias; Improvement: Post-stratify to match totals even though some groups were never sampled.

BBias: Survivorship bias; Improvement: Include abandoned calls (hang-ups) and record wait time until hang-up so the sample includes failures too.

CBias: Voluntary response bias; Improvement: Randomly select participants and directly contact them instead of using an open call for volunteers.

DBias: Convenience sampling; Improvement: Use a random sample from the full target population (not just the easiest-to-reach people).

Solution & Explanation:The main issue is Survivorship bias because the data include only the cases that remain and ignore failures or dropouts. To reduce this bias, Include abandoned calls (hang-ups) and record wait time until hang-up so the sample includes failures too.

Problem 2Difficulty: Mastery

Which option correctly identifies the main source of bias and the best improvement to reduce it?

ABias: Recall bias; Improvement: Shorten the recall time or use logs/records instead of relying on memory.

BBias: Convenience sampling; Improvement: Use a random sample from the full target population (not just the easiest-to-reach people).

CBias: Measurement bias; Improvement: Keep the same sample but run more calculations to reduce error.

DBias: Measurement bias; Improvement: Place sensors using a standardized placement plan (sun/shade, height) and sample locations that represent the whole neighborhood.

Solution & Explanation:The main issue is Measurement bias because the measuring tool or procedure introduces a consistent error or inconsistency in the data. To reduce this bias, Place sensors using a standardized placement plan (sun/shade, height) and sample locations that represent the whole neighborhood.

Problem 3Difficulty: Mastery

Which option correctly identifies the main source of bias and the best improvement to reduce it?

ABias: Nonresponse bias; Improvement: Increase the response rate with follow-ups and multiple contact methods, and check for differences from nonresponders.

BBias: Undercoverage; Improvement: Increase precision by measuring more digits (without addressing bias).

CBias: Undercoverage; Improvement: Distribute the survey to a random sample through channels all students use (homeroom, school email) and provide multiple access points.

DBias: Convenience sampling; Improvement: Use a random sample from the full target population (not just the easiest-to-reach people).

Solution & Explanation:The main issue is Undercoverage because some parts of the target population have little or no chance to be included in the data. To reduce this bias, Distribute the survey to a random sample through channels all students use (homeroom, school email) and provide multiple access points.
