Two sets of Powerpoint slides. The first covers measures of central tendency: mean, median and mode. The second is expected to follow the first and covers measures of dispersion, including interquartile range, variance and standard deviation, skewness and kurtosis before concluding with a discussion of how to use descriptive statistics to compare survey responses across multiple items.These slides include several examples from surveys conducted in Canada, so these slides are best for use by Canadians. An alternative version of these slides are designed for Americans.

A battery of multiple choice questions that can be used as a problem set or as part of a test. The questions require students to identify the level of measurement of several questions, identify which measure of central tendency is most approriate, and/or identify the correct measure. Most questions draw from sample items. Two questions are designed for classes that are learning how to complete recoding using SPSS syntax. These questions can be easily modified for other software packages. Answers included.

The second is expected to follow the first and covers measures of dispersion, including interquartile range, variance and standard deviation, skewness and kurtosis before concluding with a discussion of how to use descriptive statistics to compare survey responses across multiple items. These slides include examples drawn from aggregate country data, survey data from or about the United States, or items that Americans would easily understand. An alternate set of slides is almost the same, but draws primarily from Canadian examples.
