Data Science Fundamentals

Univariate analysis/visualization examines a single field or variable at a time, producing summary statistics such as mean, median, mode, frequency distribution, min/max, and standard deviation for that field. Because it is applied independently to each column in a dataset, it yields a summary aggregate per field. Bivariate visualization instead explores the relationship between two variables, and multivariate visualization explores relationships among three or more variables, neither of which focuses on summarizing individual fields in isolation.
