The sample material is from Lesson 2 of this unit. Students are introduced to the normal distribution and its characteristics (symmetry and the relationship between the mean and the median). Students learned to measure variation using the standard deviation in Lesson 1 and now in Lesson 2 learn to interpret the number of standard deviations from the mean as a measure of location.
Throughout the curriculum, interesting problem contexts serve as the foundation for instruction. As lessons unfold around these problem situations, classroom instruction tends to follow a common pattern as elaborated under Instructional Design.
You will need the free Adobe Acrobat Reader software to view and print the sample material.
Contact Adobe with any technical questions about their software or its installation.
In Course 4, students extend their understanding of the binomial distribution and how the binomial distribution is used in statistical inference to test a single proportion and to compare two treatments in an experiment.
