The third area of statistical style analysis is chronology. Here again the statistics used can be either descriptive or inferential. A description quantifies and measures the changes in a body of work, usually of a single author. The point here is that an author's work changes in a predictable manner. An inferential study uses these descriptions of change to place an author's work into chronological order where that chronology is unknown or disputed. By identifying a pattern of change, and by measuring and quantifying that change, the author's work can then be put in chronological order. An assumption underlying inferential chronological studies is that an author's work is rectilinear, in other words, there is a linear progression in the change in an author's style. Furthermore, the idea of change needs to be reconciled with the idea of the author's style remaining constant in author attribution studies.

In film, chronology studies can be used descriptively to identify a change in style across a director's work. The most obvious example is charting the change of any shot parameter across a director's career, such as average shot length, distribution of shot scales, or use of camera movement.
