Chapter 2: Problem 26

The authors of the paper "Popular Video Games: Quantifying the Presentation of Violence and its Context" (Journal of Broadcasting \& Electronic Media [2003]: 58-76) investigated the relationship between video game rating - suitable for everyone (E), suitable for 13 years of age and older \((\mathrm{T})\), and suitable for 17 years of age and older \((\mathrm{M})-\) and the number of violent interactions per minute of play. The sample of games examined consisted of 60 video games- the 20 most popular (by sales) for each of three game systems. The researchers concluded that video games rated for older children had significantly more violent interactions per minute than did those games rated for more general audiences. a. Do you think that the sample of 60 games was selected in a way that makes it reasonable to think it is representative of the population of all video games? b. Is it reasonable to generalize the researchers' conclusion to all video games? Explain why or why not.

Short Answer

Expert verified
The sample of 60 games, selected based on sales from only three gaming systems, might not be representative of all video games due to potential selection bias and limitations. Therefore, it may not be entirely reasonable to generalize the researchers' conclusion to all video games.

Step by step solution

01

Evaluate the selection of the sample size

According to the exercise, a sample of 60 video games was selected for the study, encompassing the 20 most popular games each from three different systems. The representativeness of the sample depends on whether it accurately reflects the characteristics of the entire population of video games. However, the selection here only considers popularity by sales which means it may overlook less popular but still relevant games in different categories. In addition, the sample only includes games from three systems, which may not cover all the gaming platforms.
02

Assess the legitimacy of generalizing results

Based on the sample size and the selection process, it can be potentially problematic to generalize the research conclusion to all video games. Reasons include potential bias introduced from using sales figures to select popular games and only including games from three systems. Furthermore, the exercise does not specify whether the distribution of ratings (E, T, M) in the sample mirrors that of the general population of video games.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Sampling
When conducting research about video games and violence, selecting the right sample is crucial. In this study, a total of 60 video games were chosen, 20 from each of three different game systems. The idea behind sampling is to pick a group from which you can safely draw conclusions about the entire population. Here, the sample reflects only the most popular games based on sales. This focus on popular games might mean missing out on other important titles. Secondly, the decision to only include three gaming systems limits the scope, potentially leaving out insights from other platforms. While 60 may seem like a sufficient number, the selection criteria can introduce bias, affecting the study's outcomes.
Population Representation
The concept of population representation relates to how well a sample mirrors the larger group it stands for. In the context of this study on video game violence, the selected 60 games may not represent the broader video game market. Since popularity votes and covers only three systems, some essential aspects are possibly left unseen. Ideally, for an accurate representation, the sample should include a diverse range of games. These should span different genres, platforms, and popularity levels. This diversity ensures that the findings can be more fairly applied to the entire group. When a sample lacks representation, it can lead to skewed conclusions that do not reflect the true nature of the whole population.
Generalizability
Generalizability refers to the extent to which findings from a study can be applied to the general population. In our case, the study's conclusions about video games rated for older children being more violent might not hold true across all video games. Due to the specific choice of popular games on select systems, it's challenging to say these findings represent all video games. It's essential to question whether a small and possibly narrow sample can lead to universally applicable conclusions. Reliable generalizability requires a sample that captures the diversity of the overall gaming market. Otherwise, results may only speak accurately for the specific sample rather than for all video games.
Game Ratings
Game ratings help guide users about the content's suitability for different age groups. The study in question focused on games rated for everyone (E), teens (T), and mature audiences (M). It's important to understand that these ratings serve as a general guideline based on age-appropriate content. In the context of this research, the ratings should align with the content being measured 鈥� violence, in this case. If a game rated for teens shows significant violence, it should reflect in the research outcomes. However, ratings can sometimes vary by cultural standards and evaluating boards, which could affect the consistency in measuring such characteristics like violence across games. Therefore, when using ratings as a core part of research, one should account for these variations.
Statistical Bias
In any study, statistical bias can affect the validity of conclusions. In this exercise, bias may have been introduced through the criteria used to select the games. Choosing solely the most popular titles and limiting the selection to three gaming systems can lead to systematic biases. This means some games which might give different results have been unwittingly excluded. Statistical bias occurs when certain elements are overrepresented or underrepresented, leading to misleading outcomes. It's vital for researchers to identify and mitigate these biases to ensure that their findings stand true across broader contexts. This helps create more accurate and reliable generalizations across the entire population of video games.

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 \(11999 \mathrm{~J}: 18-27),\) sensory tests were conducted using 40 college student volunteers at Texas Women's University. Give three reasons, apart from the relatively small sample size, why this sample may not be ideal as the basis for generalizing to the population of all college students.

Based on a survey conducted on the DietSmart .com web site, investigators concluded that women who regularly watched \(O\) prah were only one-seventh as likely to crave fattening foods as those who watched other daytime talk shows (San Luis Obispo Tribune, October 14,2000\()\). a. Is it reasonable to conclude that watching \(O\) prah causes a decrease in cravings for fattening foods? Explain. b. Is it reasonable to generalize the results of this survey to all women in the United States? To all women who watch daytime talk shows? Explain why or why not.

An experiment was carried out to assess the effect of Sweet Talk, a text messaging support system for patients with diabetes ("A Randomized Controlled Trial of Sweet Talk," Diabetic Medicine \([2 \mathrm{OO} 6]: 1332-1338) .\) Participants in the experiment were 92 patients, age 8 to \(18,\) with type I diabetes who had been on conventional insulin treatment for at least one year. Participants were assigned at random to one of three experimental groups: Group 1: continued conventional insulin therapy Group 2: continued conventional insulin therapy with Sweet Talk support Group 3: followed a new intensive insulin therapy with Sweet Talk support One response variable was a measure of glucose concentration in the blood. There was no significant difference in glucose concentration between groups 1 and \(2,\) but group 3 showed a significant improvement in this measure compared to groups 1 and 2 . a. Explain why it is not reasonable to attribute the observed improvement in group 3 compared to group 1 to the use of Sweet Talk, even though subjects were randomly assigned to the three experimental groups. b. How would you modify this experiment so that you could tell if improvement in glucose concentration was attributable to the intensive insulin therapy, the use of Sweet Talk, or a combination of the two? c. Draw a diagram showing the structure of the modified experiment from Part (b).

Do ethnic group and gender influence the type of care that a heart patient receives? The following passage is from the article "Heart Care Reflects Race and Sex, Not Symptoms" (USA Today, February 25,1999 , reprinted with permission): Previous research suggested blacks and women were less likely than whites and men to get cardiac catheterization or coronary bypass surgery for chest pain or a heart attack. Scientists blamed differences in illness severity, insurance coverage, patient preference, and health care access. The researchers eliminated those differences by videotaping actors - two black men, two black women, two white men, and two white women - describing chest pain from identical scripts. They wore identical gowns, used identical gestures, and were taped from the same position. Researchers asked 720 primary care doctors at meetings of the American College of Physicians or the American Academy of Family Physicians to watch a tape and recommend care. The doctors thought the study focused on clinical decision making. Evaluate this experimental design. Do you think this is a good design or a poor design, and why? If you were designing such a study, what, if anything, would you propose to do differently?

In 2000 , the chairman of a California ballot initiative campaign to add "none of the above" to the list of ballot options in all candidate races was quite critical of a Field poll that showed his measure trailing by 10 percentage points. The poll was based on a random sample of 1000 registered voters in California. He is quoted by the Associated Press (January 30, 2000) as saying, "Field's sample in that poll equates to one out of 17,505 voters," and he added that this was so dishonest that Field should get out of the polling business! If you worked on the Field poll, how would you respond to this criticism?
