Chapter 1: Q32. (page 52)

Guilt in decision making. The effect of guilt emotion on how a decision maker focuses on the problem was investigated in the Journal of Behavioral Decision Making (January 2007). A total of 171 volunteer students participated in the experiment, where each was randomly assigned to one of three emotional states (guilt, anger, or neutral) through a reading/writing task. Immediately after the task, the students were presented with a decision problem (e.g., whether or not to spend money on repairing a very old car). The researchers found that a higher proportion of students in the guilty-state group chose to repair the car than those in the neutral-state and anger-state groups.

a. Identify the population, sample, and variables measured for this study.

b. Identify the data-collection method used.

c. What inference was made by the researcher?

d. In later chapters you will learn that the reliability of an inference is related to the size of the sample used. In addition to sample size, what factors might affect the reliability of the inference drawn in this study?

Short Answer

Expert verified

a. Population is the students, the sample size is 171, and the variables are guilt, anger, and neutral.

b. Reading and writing tasks

c. Compared to the other two groups, maximum students belonging to the guilty-state group chose for repairing the car.

d. Sample size and the presence of sampling errors.

Step by step solution

01

Identifying of population, sample, and variables

The total number of students is the total population, out of which171have been selected by the researchers. This is the sample. The variables are the emotional states:guilt, anger, and neutral.

02

Determining the data-collection method

After randomly selecting 171 students from the group of students, for collecting the data, the researchers have made the studentsread and write certain specified things. The tasks were then meticulously examined by the researchers to find out which students would repair a car based on their emotions.

03

Indicating the inference

After meticulously conducting the research by the researchers, it has been deduced thatmaximum students of the guilt-state group will repair the cars. In the other groups, the number of students who chose to repair the cars is comparatively low.

04

Specifying the reliability of inference

Theinference is reliable because the sample size is very large than 30, and the sample size with more than 30 elements is often considered reliable. The researchers must note whether any errors have occurred while forming the sample or not. This relates to the concept that if the errors are more, the inference will not be considered reliable.

Drafting NFL quarterbacks. The National Football League (NFL) is a lucrative business, generating an annual revenue of about $8 million. One key to becoming a financially successful NFL team is drafting a good quarterback (QB) out of college. The NFL draft allows the worst-performing teams in the previous year the opportunity of selecting the best quarterbacks coming out of college. The Journal of Productivity Analysis (Vol. 35, 2011) published a study of how successful NFL teams are in drafting productive quarterbacks. Data were collected for all 331 quarterbacks drafted between 1970 and 2007. Several variables were measured for each QB, including draft position (one of the top 10 players picked, selection between picks 11 and 50, or selected after pick 50), NFL winning ratio (percentage of games won), and QB production score (higher scores indicate more productive QBs). The researchers discovered that draft position is only weakly related to a quarterback鈥檚 performance in the NFL. They concluded that 鈥渜uarterbacks taken higher [in the draft] do not appear to perform any better.鈥�

a. What is the experimental unit for this study?

b. Identify the type (quantitative or qualitative) of each variable measured.

c. Suppose you want to use this study to project the performance of future NFL QBs. Is this an application of descriptive or inferential statistics? Explain.

Parking at a university. Parking at a large university has become a big problem. The university's administrators want to determine the average parking time of its students. An administrator inconspicuously followed 250 students and carefully recorded the time it took them to find a parking spot.

a. What is the population of interest to the university administration?

b. Identify the sample of interest to the university administration.

c. What is the experimental unit of interest to the university administration?

d. What is the variable of interest to the university administration?

Who is better at multi-tasking? In business, employees are often asked to perform a complex task when their attention is divided (i.e., multi-tasking). Human Factors (May 2014) published a study designed to determine whether video game players are better than non鈥搗ideo game players at multi-tasking. Each in a sample of 60 college students was classified as a video game player or a nonplayer. Participants entered a street crossing simulator and were asked to cross a busy street at an unsigned intersection. The simulator was designed to have cars traveling at various high rates of speed in both directions. During the crossing, the students also performed a memory task as a distraction. Two variables were measured for each student: (1) a street crossing performance score (measured out of 100 points) and (2) a memory task score (measured out of 20 points). The researchers found no differences in either the street crossing performance or memory task score of video game players and non-gamers. 鈥淭hese results,鈥� say the researchers, 鈥渟uggest that action video game players [and non-gamers] are equally susceptible to the costs of dividing attention in a complex task鈥�.

a. Identify the experimental unit for this study.

b. Identify the variables measured as quantitative or qualitative.

c. Is this an application of descriptive statistics or inferential statistics? Explain.

Give an example of unethical statistical practice.

Random-digit dialing. To ascertain the effectiveness of their advertising campaigns, firms frequently conduct telephone interviews with consumers using random-digit dialing. With this approach, a random number generator mechanically creates the sample of phone numbers to be called. Each digit in the phone number is randomly selected from the possible digits 0, 1, 2, . . . , 9. Use the procedure to generate five seven-digit telephone numbers whose first three digits (area code) are 373.
