PSY230 INTRO TO STATISTICS

Question 41 There is more than one kind of correlation coefcient, true or false. 0 0 true 0 false Question 42 Which of the following is NOT a form of reliability? 0 inter-rater reliability 0 content reliability 0 parallel forms reliability O test-retest reliability D Question 43 2 pts Cronbach's alpha refers to of measurement inter-rater internal consistency repeated measurement intra-rater D Question 44 2 pts Hypothesis testing tests the null hypothesis for based on a, which defines the region. rejection, acceptance rejection, rejection acceptance, acceptance acceptance, rejectionQuestion 45 2 pts For a one-tailed test, 0! denes the rejection region at 0 should be omitted from the analysis 0 one end of the probability density function 0 both ends of a probability density function 0 has nothing to do with a probability density function Question 46 2 pts Which of the following is NOT true regarding homogeneity of variance? 0 requires an F test and table 0 Precedes comparisons of means 0 meets the assumption for Pearson's r O is the ratio of two variances Question 47 2 pts Cell "b" represents? True null hypothesis False null hypothesis Reject null H a b Accept null H c d C Type ll error 7\Question 48 2 pts Cell "c" represents? True nu|| False null hypothesis hypothesis Reject null H Accept null H ('7 Type II error 0 fatal error 0 no error 0 Type I error Question 49 2 pts If a raw score converts to a z and a t of the same value, which is more likely to be signicant? Hint: which distribution has the smaller rejection region for the same value of z or t? ('7 t>z Question 49 If a raw score converts to a z and a t of the same value, which is more likely to be signicant? Hint: which distribution has the smaller rejection region for the same value of z or t? O t>z Question 50 Why use nonparametric tests? 0 they are more informative than interval and ratio data 0 because they are fun 0 because they can used to analyze data that are not interval or ratio O they are more likely yo give signicant results
