D. the normalized Z score. Question 4 of 20 5.0/ 5.0 Po**in**ts A psychologist conducts a survey of job satisfaction among laborers and white-collar workers us**in**g a rat**in**g scale on which 1 **in**dicates low satisfaction and 10 **in**dicates high satisfaction. The f**in**d**in**gs are that laborers have a mean job satisfaction score of 4 and a variance of 1; white-collar workers have a mean job satisfaction score of 7 and a variance of 10. Which statement MOST completely describes the mean**in**g of these numbers? • A. White-collar workers are more satisfied than laborers. • B. White-collar workers and laborers are about equally satisfied. • C. Laborers generally are less satisfied than white-collar workers, but laborers are just as likely to be highly satisfied as white-collar workers are to be highly dissatisfied. • D. Laborers are less satisfied than white-collar workers, and most laborers are about equally dissatisfied, while there is more variation **in** the satisfaction of white-collar workers. Question 5 of 20 5.0/ 5.0 Po**in**ts In a histogram, the vertical dimension shows: • A. the possible values the variable can have. • B. the **in**tensity of the variable. • C. the mean score. • D. the frequency. Question 6 of 20 5.0/ 5.0 Po**in**ts Based on the scores 1, 9, 3, 6, 1, 2, 6, 2, 2, and 8, a score of 2 is the: • A. mode. • B. median. • C. mean. • D. standard deviation. Question 7 of 20 5.0/ 5.0 Po**in**ts A psychologist who constructs a frequency table to summarize data collected on the amount of stress people have experienced **in** the last 2½ weeks is us**in**g: • A. a measure of central tendency. • B. a descriptive statistical method. • C. an **in**tuitive statistical method. • D. an **in**ferential statistical method. Question 8 of 20 0.0/ 5.0 Po**in**ts The standard deviation of the scores: 2, 0, 1, 8, and 4 is:

• A. 0.67. • B. 2.83. • C. 3. • D. 8. Question 9 of 20 5.0/ 5.0 Po**in**ts If the variance is 9, then the standard deviation is: • A. 18. • B. 81. • C. 3. • D. 4.5. Question 10 of 20 5.0/ 5.0 Po**in**ts The mode of the follow**in**g scores 3, 4, 6, 7, 10, 10, and 30 is: • A. 3 • B. 7 • C. 8.5 • D. 10 Question 11 of 20 5.0/ 5.0 Po**in**ts The length of time a person talks **in** a group discussion is an example of a(n): • A. cont**in**uous variable. • B. categorical variable. • C. transformed variable. • D. extraneous variable. Question 12 of 20 5.0/ 5.0 Po**in**ts If a psychologist study**in**g aggressive tendencies **in** people develops an **in**ventory to measure aggression, the psychologist is us**in**g scores on the **in**ventory as a(n): • A. abstract concept. • B. variable. • C. descriptive statistic. • D. **in**variable construct. Question 13 of 20 5.0/ 5.0 Po**in**ts Which of the follow**in**g student characteristics is an example of a nom**in**al variable?
