Chapter 1: Problem 64

According to the article "Effect of Preparation Methods on Total Fat Content, Moisture Content, and Sensory Characteristics of Breaded Chicken Nuggets and Beef Steak Fingers" (Family and Consumer Sciences Research Journal [1999]: 18-27), sensory tests were conducted using 40 college student volunteers at Texas Women's University. Give three reasons, other than the relatively small sample size, why it would not be a good idea to generalize any study results to the population of all college students.

Short Answer

Expert verified
Three reasons not to generalize this study's results are potential biases inherent in the sample selection, the effects of the volunteer bias given the voluntary participation, and the specific subject matter of the research being potentially unreflective of general behaviors or preferences among all college students.

Step by step solution

01

Identifying Potential Biases in Sample Selection

One reason could be the inherent biases in the sample selection. When conducting a study at a specific place (in this case, Texas Women's University), the sample might not be representative of the entire population of college students. The students in this specific University might have different lifestyles, preferences, or backgrounds that make them different from students in other universities.
02

Considering the Effect of Voluntary Participation

A second reason would be the voluntary nature of the participants affecting the outcomes of the study. Depending on the motivation behind their participation, volunteers may not be representative of all college students. This volunteer bias might skew the results, making it less applicable when generalizing to the entire college student population.
03

Understanding the Limitations of the Subject Matter

Third, the subject matter of the research might limit our ability to generalize the findings. The study examines sensory tests relating to breaded chicken nuggets and beef steak fingers. This is very specific and may not be reflective of general behaviors or preferences among all college students.

The same article referenced in Exercise 1.13 also described a study which concluded that people tend to respond differently to the following questions: Question 1: Would you rather have \(\$ 50\) today or \(\$ 52\) in a week? Question 2 : Imagine that you could have \(\$ 52\) in a week. Would you rather have \(\$ 50\) now?

Use the following information to answer. Many surgeons play music in the operating room. Does the type of music played have an effect on the surgeons' performance? The report "Death Metal in the Operating Room" (NPR, Dec. 24, 2009, www.npr.org) describes an experiment in which surgeons used a simulator to perform a surgery. Some of the surgeons listened to music with vocal elements while performing the surgery, and others listened to music that did not have vocal elements. The researchers concluded that the average time to complete the surgery was greater when music with vocal elements is played than when music without vocal elements is played. What are the experimental conditions for the experiment described? What is the response variable?

Based on a study of 2,121 children between the ages of 1 and 4 , researchers at the Medical College of Wisconsin concluded that there was an association between iron deficiency and the length of time that a child is bottle-fed (Milwaukee Journal Sentinel, November 26,2005\() .\) Describe the sample and the population of interest for this study.

For each of the statistical studies described indicate whether the study is an observational study or an experiment. Give a brief explanation for your choice. The following conclusion from a statistical study appeared in the article "Smartphone Nation" (AARP Bulletin, September 2009): "If you love your smart phone, you are not alone. Half of all boomers sleep with their cell phone within arm's length. Two of three people ages 50 to 64 use a cell phone to take photos, according to a 2010 Pew Research Center report."

A study of college students showed a temporary gain of up to nine IQ points after listening to a Mozart piano sonata. This result, dubbed the Mozart effect, has since been criticized by a number of researchers who have been unable to confirm the result in similar studies. Suppose that you want to determine if there is really is a Mozart effect. You decide to carry out an experiment with three experimental groups. One group will listen to a Mozart piano sonata that lasts 24 minutes. The second group will listen to popular music for the same length of time, and the third group will relax for 24 minutes with no music playing. You will measure IQ before and after the 24 minute period. Suppose that you have 45 volunteers who have agreed to participate in the experiment. Describe a method of randomly assigning each of the volunteers to one of the experimental groups.
