Document Summary
Discuss importance of relying on data from large samples rather than small samples or single cases. Understand and explain how the smarties activity illustrates why we use stats to analyze our sample data. Explain three errors in judgement that people commonly make. In craps , you throw two dice. if you roll 7 or 11, you win. If you roll 2, 3, or 12, you lose. With 2 dice, how many ways can you roll This continues to increase to 7, where the max ways are 6, and then it decreases to 12, where the only way is (6 - 6). Therefore, what are the odds of winning? (6/36) + (2/36) = (8/36) = 22% The 6 and 2 are the amount of ways you can score either a 7 or. Odds of losing? (1/36) + (2/36) + (1/36) = (4/36) = 11% When there is a difference in the means.
