Comparing these different sample sizes illustrates that larger samples tend to produce observed proportions that are more stable and closer to the theoretical probability. With fewer trials (like 10), random noise can cause significant deviations from the expected proportion.

Conditions: The comparison involves sample sizes of 10, 100, and 1,000 trials.; The goal is to understand the stabilization of observed proportions.

A model provides a theoretical probability, which is the expected likelihood of an outcome based on the underlying rules. An experiment provides an observed proportion, which is calculated from the actual outcomes recorded.

Conditions: The context is a short run of experiments.; Comparing theoretical probability from a model with observed proportion from data.
