Data are basically any fact that you can quantify to any degree. They can be measures, observations, numbers, and even words. Science was built on the use of data and interpreting it to find or determine naturally truths. Collecting data and the way we go about collecting data are just as important as the results we find from it. There are many ways that the collection process can interfere with the interpretation phase.
