Based off of the hit television show NUMB3RS, this lesson introduces students to the odds ratio, a method in statistics for determining if the findings of two groups are statistically significant to each other. Students will find probabilities, odds, and finally the odds ratio of two groups. As an extension, students will explore the logit function.

This set contains statistics questions regarding the normal curve, its distribution, and its applications. The student, using the correct calculation, transitions between observed x-values, standard z-scores, and normal curve areas.

In this activity, students will apply the normal density function, normal cumulative distribution function, and inverse normal cumulative function to analyze a population with a normal distribution.

Students graph normal distributions, shade desired areas, and find related probabilities. They graph Normal probability scatter plots to check the normal (linear) shape of a data distribution.
