PPT-1 st level analysis: Design matrix, contrasts, and inference

Roy Harris amp Caroline Charpentier Outline What is 1st level analysis The Design matrix What are we testing for What do all the black lines mean What do we need to include Contrasts. We usually want to answer certain questions posed by the objectives of the experiment. Irrigation experiment (a 2 x 2 factorial). 1 cm/ha applied early . (m. 1. ). 1 cm/ha applied late .

A distinction between recognition -> I remember details of learning how to calculate contrasts, like who taught me and why. and familiarity -> I have a vague notion that contrasts were described to me at some point..

A Concise Introduction to Logic. (Belmont: Thomson Wadsworth, 2008).. Predicate Logic. Before I go on to explain quantifiers, first let me address different ways of symbolizing statements. Previously, we used one letter to symbolize one statement. But there is another way to symbolize certain kinds of statements that are relevant to quantifiers. We can also symbolize statements by symbolizing the predicate and subject separately. .
