Sample Size and Limitations

Sample Size and Limitations Worksheet (Grade 6 Science, TEKS 6.2B)

Help grade 6 students judge how much they can trust a set of data. This one-page reading and activity sheet explains sample size, chance, evidence, and limitations in plain words, using real examples like testing plant food and surveying students about school lunch.

What's Inside

• A short reading on sample size, chance results, evidence, and the limitations of a study
• Activity 1: Students compare two plans for three real questions and circle the one that gives stronger evidence
• Activity 2: A word bank fill-in with chance, evidence, limitation, and sample size
• A visual answer key with answers marked in red

How Teachers Use It

Use it before students plan an investigation, when reviewing lab results, or as practice for TEKS 6.2B. Every term is taught on the page. The sheet takes about 10 minutes and prints clearly in black and white.

This worksheet is part of the Reading in Science series for grade 6. It supports TEKS 6.2B: analyze data by identifying any significant descriptive statistical features, patterns, sources of error, or limitations. Pair it with the other 6.2B sheets to build a short unit on data analysis.

Why It Works

Each sheet teaches the key terms in plain words first, then asks students to use only what the page taught. Activities stay at the circle, sort, match, and fill-in level, so students build confidence while the answer key lets teachers check work fast. The clean layout is also easy to project for a whole-class review.
