About these worksheets
Students explore the foundations of statistical thinking. Worksheets cover identifying statistical questions that require data collection, distinguishing between populations and samples, and examining whether samples are representative and unbiased. Aligned with sixth and seventh grade statistics and probability standards.
6sp1
- Decide whether a question needs data from a group of people or things to answer it.
- Tell the difference between questions with one fixed answer and questions that can have many different answers.
- Look for clues that a question expects variation, like asking about a population, a sample, or a range of results.
- Explain why a question is or is not statistical using simple reasoning.
7sp1
- Tell the difference between a population (the whole group) and a sample (part of the group).
- Spot when a sample is only a small part of the population and may not represent everyone.
- Use the words population and sample correctly when talking about data.
7sp1
- Decide whether a sample is likely to represent a whole population fairly.
- Spot sources of bias in how data is collected, like who was asked or how people were chosen.
- Explain why random sampling usually gives more reliable information than picking people conveniently.
- Use information from a sample to make a reasonable guess about what might be true for the full population.
