Q

Model

A

A visual, mathematical, or three-dimensional representation in detail of an object or
design, often smaller than the original. A model is often used to test ideas, make changes to a
design, and to learn more about what would happen to a similar, real object.

39
Rhythm
A regularly recurring sequence of events or actions, usually to represent movement o Regular – An element is repeated at the same interval o Random – the repetition of the element is random or situated at irregular intervals o Gradated – the repeated element is identical with the exception of one detail increasing or decreasing gradually with each repetition o Graduated – the repeated element becomes closer or further apart
40
Emphasis

41
Proportion
The relationship of one thing to another in size, amount, etc

43
Statistics
Collection of methods for planning experiments, obtaining data, organizing, summarizing, presenting, analyzing, interpreting, and drawing conclusions based on data
44
