# Descriptive Statistics

## Descriptive Statistics - Canadian Version

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.

## Descriptive Statistics - Multiple Choice Test Questions

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.

## Canadian Public Opinion Univariate Statistics Exercise

An assignment I used in an introduction to Canadian Politics course that required the students to go on-line to explore public opinion data from the Canadian Election Survey. This version has the students use a web-based analysis program called SDA and data that is freely available through the University of Toronto. These analyses can be completed through any browser. The instructions are lengthy and are designed for students to follow without any introduction to the software (the software is that easy). The questions are all multiple choice, so they can be graded automatically through course management software like Blackboard. An SPSS version will follow. These questions are not specific to SDA.

## Getting Started in Data Analysis

The goal of the Stata Tutorial, R Tutorial and other documents presented here is to serve as learning tools for classes requiring data analysis or for independent research requiring quantitative or statistical analysis (JPs, senior thesis, dissertation), and/or professional development.

More tutorials will be adding and will keep updating the current ones, so please check this page frequently.
