Question

Quizplus · Accepted Answer

Big data refers to extremely large data sets that may be analyzed computationally to reveal patterns, trends, and associations, especially relating to human behavior and interactions. Secondary data, on the other hand, refers to data that was collected by someone else for a different purpose but is being used by a researcher for a new study. While secondary data can be part of big data, they are not the same thing.
