Explanation & Answer
Data can be filtered in order to examine certain metrics. For example, a webadministrator looking at his database of users could filter to see the number of users from the United States ("SELECT * WHERE COUNTRY=USA"). This can aid in decision making because if say, only 3 of his users are from the USA, he might choose not to invest in marketing in the United States.
