Data and Statistics
Datasets & Statistics - What's the Difference?
Here is a visualization of statistics (percent of families receiving TANF by neighborhood). Statistics are presented in an aggregate form already, such as a table of frequencies, means, rates, or visualized as a chart or graph. To put it simply, statistics are readily available pieces of information on which a conclusion can be made.
When you want quick facts for a presentation or paper (typically used to strengthen a point), you would use typically use readily-available or easily created statistics (we have lots of table building tools). If you're planning to test a hypothesis, develop a comprehensive marketing strategy, assess the effect of a particular treatment - essentially anything that would require in-depth analysis - then you need a dataset. Just make sure that if you are using existing data or statistics (as in, you didn't collect it yourself), that you cite it properly.
This guide is designed to help you find both statistics and datasets. Some of the resources provided are limited to the Johns Hopkins domain and will require you to log in with your JHED ID and password in order to use them. However, many data sources that are available from government agencies, think tanks, non-profits, etc. are open access. This guide is not exhaustive, but designed to provide you with a solid starting point on possible sources. If you are not finding what you are looking for, please contact the librarian (see the box on the left).
