Students learn how toÂ estimate probabilities from experimental data to check for bias.

ÂLater, as learning progresses they consider the effect of the sample size and relative frequency.

**ifferentiated Learning Objectives**

- All students should be able to estimate a probability from experimental data.
- Most students should be able to estimate a probability from experimental data and identify bias.
- Some students should be able to understand how sample size affects relative frequency.
