Multiple Choice

A dataset where each row is an instance and each column is a feature is described as which format?

In wide format, each row represents a single observation, and every feature has its own column. This matches the description you gave: one row per instance and each column a feature. It’s the common tabular layout used in many analyses and models because all the variables sit side by side in one record. If data were in long (or narrow) format, you’d see multiple rows per instance, with additional columns indicating the variable name and its value, which isn’t what the description specifies. Pivoted format refers to reshaping data between wide and long, but the arrangement described is the wide format.
