Title: The Graded Naming Test and sociocultural differences: Researchers often use z tests to compare their Post by: AnaDalia on Feb 26, 2019 The Graded Naming Test and sociocultural differences: Researchers often use z tests to compare their samples to known population norms. The Graded Naming Test (GNT) asks respondents to name objects in a set of 30 black-and-white drawings. The test, often used to detect brain damage, starts with easy words like kangaroo and gets progressively more difficult, ending with words like sextant. The GNT population norm for adults in England is 20.4. Roberts (2003) wondered whether a sample of Canadian adults had different scores than adults in England. If they were different, the English norms would not be valid for use in Canada. The mean for 30 Canadian adults was 17.5. For the purposes of this exercise, assume that the standard deviation of the adults in England is 3.2.
a. Conduct all six steps of a z test. Be sure to label all six steps. Title: Re: The Graded Naming Test and sociocultural differences: Researchers often use z tests to compare t Post by: bio_man on Feb 26, 2019 Hi AnaDalia (https://biology-forums.com/index.php?action=profile;u=840786)
