Searching for data
When searching for data, ask yourself these questions...
Who has an interest in collecting this data?
- If federal/state/local agencies or non-governmental organizations, try locating their website and looking for a section on research or data.
- If social science researchers, try searching ICPSR.
What literature has been written that might reference this data?
- Search a library database or Google Scholar to find articles that may have used the data you're looking for. Then, consult their bibliographies for the specific name of the data set and who collected it.
Is the data...
- From a reliable source? Who collected it and how?
- In a format I can use for analysis or mapping? Will it require any file conversion or editing before I can use it?
- Comparable to other data I'm using (if any)? What is the unit of analysis? What is the time scale and geography? Will I need to recode any variables?
The following professional-grade software packages allow you to manipulate and visualize data in very complex ways:
- SAS - Powerful statistical analysis and data management tool, uses command-line interface, particularly good for ANOVA
- Stata - Powerful statistical analysis, not as strong at data management as SAS
- SPSS - Relatively sophisticated data analysis tool, with a user-friendly GUI, geared toward quantitative social sciences data
- R - Free, versatile option for data analysis and visualization
