How do researchers determine what is true based on the data they collect? This question is one of the central concerns of statistics, which uses mathematical models to draw useful conclusions about the real world.

New Zealand is an island country in the southwestern Pacific Ocean. The country geographically comprises two main landmasses ‒ that of the North and South Islands ‒ and numerous smaller islands. Overseas students need to have a student visa and a reasonable level of cash to spend in order to undertake a course of study at a New Zealand based educational institution. New Zealand educational institutions will inform the appropriate immigration authorities if a student ceases to attend their enrolled courses, who may then suspend or cancel that student's visa. Educational institutions often also exchange this enrollment and attendance data electronically with other government agencies responsible for providing student assistance.

Earning a master’s degree can take anywhere from a year to three or four years. Before you can graduate, you usually must write and defend a thesis, a long paper that is the culmination of your specialized research.
