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 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.
