- True experimentation is the best design to use to predict causal relationships. - It refers to the classic two group design in which subjects are randomly selected and randomly assigned to either and experimental or control group condition.

- Used when answering Level 3 questions when the intent is to predict and reveal a cause. The book focuses on the advancements of techniques, practices, approaches, and methodologies in machine learning. The selection first offers information on automatic algorithm/model class selection, using decision trees to improve case-based learning, GALOIS, and multitask learning.

This article discusses definitions of index and indexing and provides a systematic overview of kinds of indexes. Theories of indexing are reviewed, and the theoretical basis of both manual indexing and automatic indexing is discussed, and a classification of theories is suggested (rationalist, cognitivist, empiricist, and historicist and pragmatist theories).
