Question 2

Richard did a study of "Autobiographical Memory of School" for his master's degree thesis.In one part of Richard's study,he had 60 college students write a description of one event from their schooling (any grade,1-12).After obtaining the 60 descriptions,they were classified as shown.The expected frequency was 10 in each cell.

Question 6

James has conducted a study involving a total of 60 participants.These individuals were randomly assigned to one of three different treatment conditions--No Sound,White Noise,or Conversation.Each was then tested on a reading recall task.Because James knows his study does not meet one of the assumptions for a parametric test,what nonparametric test should he run?

Accepted Answer

A) Mann-Whitney U 
B) Spearman   
C) a Friedman   
D) Kruskal-Wallis H 
A) Mann-Whitney U 
B) Spearman   
C) a Friedman   
D) Kruskal-Wallis H

Question 8

Patricia has collected data on 30 individuals.She measured the pulse rate of 15 individuals after they had watched a violent film clip.She measured the pulse rate of the other 15 people after they had watched a non-violent film clip.Because she knows her study does not meet the assumptions for a two-tailed t-test,what nonparametric test should she run?
