Statistics Notes for Data Science and ML

Exploratory data analysis

• anecdotal evidence: Evidence, often personal, that is collected casually rather than by a well-designed study.

• population: A group we are interested in studying. “Population” often refers to a group of people, but the term is used for other subjects, too.

• cross-sectional study: A study that collects data about a population at a particular point in time.

• cycle: In a repeated cross-sectional study, each repetition of the study is called a cycle.
