For Discussion:1. Is the distribution of the results of a game of chance, such as Chutes and Ladders, really a

normal distribution?

2. Why doesn’t the graph of hemoglobin levels in the Swedish men follow a perfectly smooth curve?

• Things to Remember •

1. The normal distribution is what you get when you add up a large number of random events.

2. The normal distribution describes the variation of many natural phenomena, such as the hemoglobin levels.

3. The normal distribution also describes the variation in results of a study were we to repeat it many times.
