Welcome Stat 3220!
This guide will help you discovery and evaluate sources.
The presentation slides are available. The slides cover the general concepts about finding and evaluating data. (Be sure to view the Speaker Notes.) This research guide points to specific resources available through the library or publicly.

Citation Guide - How to Cite within a paper
Unlike Many other disciplines, Math and Statistics don't have a single citation style in publications. However, we recommend you use APA citation style. We recommend using a citation generator to create accurate citations you can copy into your paper. You will have an in-text citation in your paper where you reference your website/journal/data source/etc. At the end of your paper you will have a "References" section where you will have the full citation.
Example-
In-text citation:
"Role-play can help children learn techniques for coping with bullying" (Kraiser, 2011)
Reference Entry:
Kraizer, S. (2011). Preventing bullying. Retrieved from http://safechild.org/categoryparents/preventing-bullying/
- Citation Machine
Citation Machine is a user friendly citation manager. Enter your information and Citation Machine spits out your citation. - Purdue Online Writing Lab
For many years, Purdue University's Online Writing Lab has been an authority on citation formats and styles. At the top of this page - APA Homepage
If you want to read more documentation about APA style, you can find it on the American Psychological Association Homepage
Library Licensed Datasets
These are data sources available to you through UVA Library. They cover a broad range of topics.
- ICPSR This link opens in a new windowThe Inter-university Consortium for Political and Social Research (ICPSR) provides a vast archive of social science data for research and instruction. Users may view documentation, download raw data, and search a bibliography of data-related literature. (You must create a personal ICPSR account with your virginia.edu email address in order to download data.)
- Social Explorer This link opens in a new windowInteractive Maps and Reports provide easy access to demographic information about the United States. Data comes from the Census beginning in 1790 and from the Religious Congregations and Membership Study beginning in 1980. Also has crime and health data.
- Data-Planet This link opens in a new windowThe Data-Planet repository contains over 18.9 billion datapoints from over 400 databases sourced from 70 public and private organizations. The datasets contained in Data-Planet are structured and homogenized to permit correlation of multiple, diverse indicators. The Data-Planet technology and information architecture provides powerful tools to interpret and visualize that data. The repository continues to grow regularly with the addition of new datasets drawn from public and private sources.
- Library Licensed Downloadable DatasetsAll the library licensed downloadable datasets are listed here. Of particular interest would be election data, Historical Business Data, and Gallup Survey Data.
Government Data
- Research Data Services: Find DataThese library pages are organized by theme and include sources available from government sources.
- Data.govUS federal government's open data portal
- Our World in DataNice resource for finding international data on all kinds of policy-related topics. Note that you can download the data as a CSV file. Check out the Source tab for information about the data file and the original source of the data. Because they use data from third parties, you might want to check out how to cite OWiD sources correctly.
US Census
For those of you using the US Census, you might want to check out these resources:
- Social Explorer This link opens in a new windowInteractive Maps and Reports provide easy access to demographic information about the United States. Data comes from the Census beginning in 1790 and from the Religious Congregations and Membership Study beginning in 1980. Also has crime and health data.
Data from News Sources
Also see News sources’ GitHub repos: NYTimes, Washington Post, BuzzFeed News, etc.
- BuzzFeedNews/everything repoAn index of all of BuzzFeed's open-source data, analysis, libraries, tools, and guides.
Academic Literaure
Every empirical academic paper is going to have a methods section. Look for articles similar to a topic you are interested in, and check the methods section. What data are they using?
Here is a real-life example. A group of students asked Jenn about Major League Baseball injuries, and she found this: Injury Rates in Major League Baseball During the 2020 COVID-19 Season. The very first line of the Methods section states, “Data from the 2018-2020 MLB transaction reports were extracted online at mlb.com/transactions.”
Remember to Iterate
Start in one place and keep iterating. Use the first place to see if sources are cited, and work from there.
Statista is a great place to try this strategy. Statista only offers basic statistics (tables and charts, not full datasets). However, they always cite their sources. Keep digging at the source to see if you can find an original dataset. You can use the same strategy with PolicyMap as well.
- Statista This link opens in a new windowStatista.com consolidates statistical data on over 80,000 topics from more than 22,500 sources.
- PolicyMap This link opens in a new windowPolicyMap is an online data and mapping tool that enables government, commercial, non-profit and academic institutions to access data about communities and markets across the US. Use it for research, market studies, business planning, site selection, grant applications and impact analysis.
