In order to control for potential order effects, a Latin square design is utilized. In particular, two randomly constituted squares are formed with three monkeys randomly assigned to each square and also randomly assigned to the particular row of the square that assigns the order that they are exposed to treatment<\/p>\n<p>The hypothesis of primary interest is whether the drugs differ in their effectiveness in controlling aggression in the monkeys. Thus, the test of the condition main effect is of primary interest. The current procedure reproduces the results for test of the condition main effect shown on page 615.<\/p>\n<h4>1.\u00a0Click Analyze, then General Linear Model, then Univariate.<\/h4>\n<p><!--more--><\/p>\n<figure id=\"attachment_564\" class=\"wp-caption alignnone\" data-shortcode=\"caption\"><img decoding=\"async\" class=\"alignnone size-full wp-image-564\" src=\"https:\/\/designingexperiments.files.wordpress.com\/2016\/02\/image002-1.gif?w=700\" alt=\"image002 (1).gif\" \/><figcaption class=\"wp-caption-text\">Choose General Linear Model, Univariate<\/figcaption><\/figure>\n<h4>2.
