What is a Master’s Thesis
• document that presents the author's research.
• is submitted to obtain a degree
• The word thesis comes from the Greek word , meaning “position” (intellectual proposition)
Program in Architectural AcousticsCommunication Acoustics and Aural Architecture Research Laboratory
Research
• is the process to gather new knowledge and to establish new facts
• uses a systematic approach to find and evaluate new facts
• typically uses the scientific method
Program in Architectural AcousticsCommunication Acoustics and Aural Architecture Research Laboratory
The Scientific Method/Method of Inquiry
• refers to a body of well-established techniques to gather new knowledge, correct or refine existing knowledge
• usually includes data collection, through observation and/or experimentation, and formulating and evaluating hypotheses (e.g., using statistical methods).
• All steps to gather new knowledge should be repeatable, in order to be verifiable. Consequently researchers are expected to share all of their data and documents (full disclosure).

hy·poth·e·sis
• a tentative assumption made in order to draw out and test its logical or empirical consequences
Etymology: Greek, from hypotithenai to put under, suppose
date: circa 1656

the·o·ry
• a plausible or scientifically acceptable general principle or body of principles offered to explain phenomena <the wave theory of light>a hypothesis assumed for the sake of argument or investigation
• an unproved assumption
Etymology: Late Latin and Greek theoriadate: 1592

law
• a statement of an order or relation of phenomena that so far as is known is invariable under the given conditions
• a general relation proved or assumed to hold between mathematical or logical expressions
• a binding custom or practice of a community • a rule of conduct or action prescribed or formally
recognized as binding or enforced by a controlling authority
date: before 12th century
