The main tip for researching minimum wage? Check the metadata! (Metadata provides information about the data you've found). If you see information buttons or explanations of how a particular number was researched or calculated, take a moment to read & contextualize the numbers.
If you find minimum wage data in a newspaper or journal article, try to track down the official source of that number to verify. You may also want to triangulate or corroborate your information across multiple sources.
