In this activity, students will learn four characteristics of a normal curve: the distribution is symmetric and mound-shaped; the mean and median are approximately equal; the distribution meets the 68-95.5-99.7 rule; and the normal probability plot is linear. They will use these to determine if a data set it normal.

In this activity, students will simulate a geometric distribution of rolling a die unitl a 6 appears. They will determine experimental probabilities and draw conclusions about the number of rolls it takes for the first 6 to appear. Students will then use the GeomPdf command to calculate the theoretical probabilities and use a scatter plot to draw conclusions. They will also calculate expected value.

Students use the Poisson distribution to determine the probabilities for various numbers of hurricanes hitting the United States in a given year. Students will also explore the graph of the Poisson distribution and how it behaves.

Students will compare two distributions. Graphical and numerical representations will be used to draw conclusions. Students will graph histograms side-by-side to make comparisons based on shape, center, and spread. Students will graph box plots on the same axes comparing shape, spread, and the five-number summary.

In this activity, students will be introduced to density curves as a simple analysis of a data set. They also will investigate where the median and mean lie on symmetric or skewed graphs.
