I earned my undergraduate degree in mechanical engineering and then went on to earn a master's in applied mathematics and statistics, working as a data analyst / scientist. Throughout that process, I noticed that the field seemed to lack a consistent and precise vocabulary. This project was intended to clarify and define that basic data science vocabulary. It is by no means comprehensive but tries to cover the major points of ambiguity and common terminology used in the field.

• Add "target" as a synonym for output variable
• Disambiguate "unique"
• Add "validation" and "scoring"
• Add "random" and "variable" slides in the Random Variable section
