Worksheet Overview & Skills Covered

Core academic competencies and curriculum alignment

This Biology Science worksheet provides structured practice on 10.6 Statistics, Error, and Uncertainty. Students are guided through targeted exercises that build foundational understanding, computational accuracy, and critical thinking skills.

Statistics, Error, and Uncertainty: Students interpret averages, range, percent change, variation, sources of error, limitations, and uncertainty in biological data sets. Rigor range: standard inquiry checks through honors/Pre-AP/AP-ready experimental reasoning.

Sample Practice Problems

Below are sample questions representative of the exercises included on this worksheet and related 10.6 Statistics, Error, and Uncertainty skill assessments:

Problem 1Difficulty: Mastery

Two survival groups are combined. Pond A has 8 survivors out of 10 organisms, and Pond B has 45 survivors out of 90 organisms. What is the correct overall survival percentage?

A65%

B30%

C130%

D53%

Solution & Explanation:Overall survival must be weighted by the number of organisms: (8 + 45) survivors out of (10 + 90) organisms = 53 out of 100, or 53%. Averaging 80% and 50% gives the misleading unweighted value 65%.

Problem 2Difficulty: Mastery

An incubator is warmer near the door. A student places all control plates near the back and all treatment plates near the door. Which improvement best reduces location-related uncertainty?

APlace all treatment plates near the warmest spot to strengthen the effect.

BUse no labels so the groups cannot be identified later.

CRandomize plate positions or rotate plates among incubator locations.

DMeasure only the plates with the largest colonies.

Solution & Explanation:Position in the incubator could affect growth. Randomizing or rotating plate locations prevents position from being confounded with treatment.

Problem 3Difficulty: Mastery

A planned data table shows Control mean = 52, range = 48-56, n = 25; Treatment mean = 60, range = 40-80, n = 25. Which claim is best supported?

AThe treatment is better for every sample because its mean is higher.

BThe treatment has a higher mean but much greater variation, so consistency is uncertain.

CThe control has the higher mean because its range is narrower.

DThe sample sizes prove there is no variation.

Solution & Explanation:The treatment mean is higher, but its wide range shows that individual results vary greatly. A careful claim includes both center and spread.
