Chapter 9: Q6E (page 528)

Drafting NFL quarterbacks. Refer to the Journal of Productivity Analysis (Vol. 35, 2011) study of how successful NFL teams are in drafting productive quarterbacks, Exercise 1.26 (p. 51). Recall that the researchers measured two variables for each of the 331 quarterbacks drafted between

1970 and 2007: (1) Draft position (Top 10, between picks 11 and 50, or after pick 50) and (2) QB production score (where higher scores indicate more productive QBs). Suppose we want to compare the mean production score

of quarterbacks in the three draft position groups. Identify each of the following elements for this study:

a. Response variable

b. Factor(s)

c. Treatments

d. Experimental units

Short Answer

Expert verified

d. The experimental unit is a quarterback in an NFL team.

Step by step solution

01

Given Information

A study of how successful NFL teams are in drafting productive quarterbacks is provided.

02

Definition

An experimental unit is an object on which the response and factors are observed or measured.

03

Identifying the experimental unit

d.

The experiment is regarding the success of NFL teams in drafting productive quarterbacks. The measurements on the quarterback production score are taken.

Therefore, the experimental unit is a quarterback in an NFL team.

a. How many factors are used in the experiment?

b. Can you determine the factor type(s)鈥攓ualitative or quantitative鈥攆rom the information given? Explain.

c. Can you determine the number of levels used for each factor? Explain.

d. Describe a treatment for this experiment and determine the number of treatments used.

Forecasting electrical consumption. Two different methods of forecasting monthly electrical consumption were compared and the results published in Applied Mathematics and Computation (Vol. 186, 2007). The two methods were Artificial Neural Networks (ANN) and Time Series Regression (TSR). Forecasts were made using each method for each of 4 months. These forecasts were also compared with the actual monthly consumption values. A layout of the design is shown in the next table. The researchers want to compare the mean electrical consumption values of the ANN forecast, TSR forecast, and Actual consumption

a. Identify the experimental design employed in the study.

Value perceptions of consumers (cont鈥檇). Refer to Exercise 9.10. In addition to the factor, Type of advertisement

(within-store price promotion and between-store price promotion), the researchers also investigated the impact of a second factor鈥擫ocation where ad is read (at home or in the store). About half of the consumers who

were assigned to the within-store price promotion read the ad at home, and the other half read the ad in the store. Similarly, about half of the consumers who were assigned to the between-store price promotion read the ad at home, and the other half read the ad in the store. In this second

experiment, the goal was to compare the average discount values of the groups of consumers created by combining Type of advertisement with Location.

a. How many treatments are involved in this experiment?

b. Identify the treatments.

What is the difference between an observational experiment and a designed experiment?

Accounting and Machiavellianism. A study of Machiavellian traits in accountants was published in Behavioral Research in Accounting (January 2008). Recall (from Exercise 1.33, p. 52) that Machiavellian describes negative character traits such as manipulation, cunning, duplicity, deception, and bad faith. A Mach rating score was determined for each in a sample of accounting alumni of a large southwestern university. The accountants were then classified as having high, moderate, or low Mach rating scores. For one portion of the study, the researcher investigated the impact of both Mach score classification and gender on the average income of an accountant. For this experiment, identify each of the following:

a. Experimental unit

b. Response variable

c. Factors

d. Levels of each factor

e. Treatments
