a. Pearson product-moment correlation; Spearman rank-order correlation b. Spearman rank-order correlation; Pearson product-moment correlation c. Phi; Spearman rank-order correlation d. Point-biserial correlation; Spearman rank-order correlation If both variables are measured on a nominal scale, what type of correlation coefficient is appropriate? a. Spearman's rank-order correlation coefficient b. phi coefficient c. point-biserial correlation coefficient d. none, because correlations cannot be computed on nominal data Suppose that the correlation between height and weight for adults is +.75 . What proportion (or percent) of the variability in weight is accounted for by the relationship with height? a. 75 b. 25 c. 56 d. unable to determine The _____ is a measure of the proportion of variance in one of the variables that is accounted for by the other variable. a. Spearman rank-order correlation coefficient b. coefficient of determination c. point-biserial correlation coefficient d. Pearson product-moment correlation coefficient In a psychology class of 100 students, test scores are normally distributed with a mean of 80 and a standard deviation of 5 . Approximately what percentage of students have scores between 70 and 90? a. 68 b. 80 c. 95 d. 99 Karen's first psychology exam score is 1 standard deviation from the mean in a normal distribution. The test has a mean of 75 and a standard deviation of 5 . Karen's percentile rank would be: a. 16. b. 54. c. 70. d. cannot say from the information given Approximately what percentage of scores are between z=1 and z=2? a. 50 b. 68 c. 16 d. 13.5 Rich's first psychology exam score is +1 standard deviation from the mean in a normal distribution. The test has a mean of 60 and a standard deviation of 6 . Rich's percentile rank would be approximately: a. 70. b. 84. c. 66. d. Cannot say from the information given. If the average height for women is normally distributed with a mean of 65 inches and a standard deviation of 2.5 inches, then approximately 95 of all women should be between _____ and _____ inches in height. a. 62.5; 67.7 b. 60; 70 c. 57.5; 72.5 d. Cannot say from the information given. Faculty in the psychology department at State University consume an average of 5 cups of coffee per day with a standard deviation of 1.5 .
