Data consists of raw information, either quantitative or qualitative. Statistics are calculated from data.
For example, you might see a table showing the number of people who voted in the 2012 elections, with one number for each state. This is data. That data could then be used to calculate a statistic -- for example the average number of people who voted across all the states.
Knowing which type of information you're looking for is important -- it will greatly aid in your search!
