Statistical information is often published by governments or other non-profit organizations. Typically this is available on the internet for free. This statistical information can be found with Google or any other search engine. You can make your searching even easier by using a few search tips.
Google and other search engines let you restrict your search to certain addresses. You can use this in a number of ways.
First, you may know that many U.S. government websites have addresses that end in .gov. You can tell Google to search .gov sites -- and only .gov sites -- by using the site option. Just add site:.gov to your search terms:
Only .gov websites appear: educateiowa.gov, nces.ed.gov, ed.gov., etc.
Second, maybe you know you only want to look at one government agency's site. If you know that agency's website, you can again use the site: option. Here I will search only the Bureau of Labor Statistic's website by using site:bls.gov and my search terms:
Now only pages on the bls.gov site appear.
Google can search for more than just websites. It can be used to search for files! You just need to use the filetype: option.
Statistical data is often shared as spreadsheet files. Spreadsheet files often have extensions like .xls, .xlsx or .csv. Therefore, if you wanted to find spreadsheets on test scores in Alaska, you might try a search like one of these:
This works pretty well, as you can see here:
Sometimes it might be handy to search one domain (or even one site) for just one type of file. For example, you could search only the ed.gov site for only .csv files by using this search: math test scores filetype:csv site:ed.gov
