Chapter 4: Problem 50

A common definition of "binge drinking" is 5 or more drinks at one sitting for men and 4 or more for women. An observational study finds that students who binge drink have lower average GPA than those who don't. Identify a variable that may be confounded with the effects of binge

Short Answer

Expert verified
Socioeconomic status or stress could confound the effect of binge drinking on GPA.

Step by step solution

01

Define Binge Drinking

Binge drinking is defined in this context as consuming 5 or more drinks at one sitting for men and 4 or more for women.
02

Analyze Effect on GPA

The study finds that students who engage in binge drinking generally have a lower average GPA than those who do not.
03

Explore Potential Confounding Variables

Consider factors that could influence both binge drinking and GPA. Such factors might include social engagement, stress levels, socioeconomic status, or engagement in other extracurricular activities.
04

Identify Socioeconomic Status as a Confounding Variable

Socioeconomic status might be a variable that affects both a student's likelihood to binge drink and their overall academic performance. Students from different socioeconomic backgrounds might have varying access to resources or support, which could impact both their drinking habits and GPA.
05

Consider Stress as Another Confounding Variable

Stress could lead students to binge drink as a coping mechanism, and it could also affect their academic performance, directly impacting GPA.

Key Concepts

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

Understanding Binge Drinking
Binge drinking involves consuming a large quantity of alcohol in a single sitting. For men, this typically means five or more drinks, while for women, it means four or more. This drinking behavior can have various social and health implications, and it is important to explore how it might affect academic outcomes.
  • Short-term effects can include impaired judgment and risky behavior.
  • Long-term effects might include dependency issues and negative health consequences.
Recognizing its definition helps in analyzing its potential impacts on students, particularly on their academic performance.
GPA Impact of Binge Drinking
Grade Point Average (GPA) is a crucial metric for assessing student performance. It reflects how well a student is doing in their courses over time. An observational study has shown that students who binge drink tend to have lower GPAs compared to those who do not.
Several reasons could explain this relationship:
  • Alcohol consumption might interfere with study time and focus.
  • Hangovers can lead to missed classes and reduced quality of work submitted.
These factors can collectively lower academic performance, highlighting the importance of understanding and addressing binge drinking habits.
Socioeconomic Status as a Confounding Variable
Socioeconomic status (SES) refers to a person's economic and social position, often measured by income, education, and occupation. It plays a critical role in a student's life, influencing both educational opportunities and personal choices. SES can be a confounding variable because it may impact both drinking habits and academic achievement.
Students from lower SES backgrounds might face:
  • Limited access to educational resources.
  • Different social pressures, potentially leading to higher rates of binge drinking.
Understanding SES can provide insight into why some students might struggle academically while also engaging in binge drinking.
Academic Performance and Its Influences
Academic performance is influenced by various factors beyond individual effort. Besides the immediate effects of binge drinking, external factors like family support, mental health, and even peer group dynamics can impact performance.
  • Supportive family environments can provide motivation and resources.
  • Mental health challenges might detract from a student's capacity to focus.
Exploring these influences can help identify strategies to improve academic outcomes and encourage healthier choices among students.
Observational Study Explained
An observational study explores relationships between variables without manipulating them. In the context of binge drinking and GPA, researchers observe natural behaviors and outcomes rather than implementing interventions.
This method helps to:
  • Identify potential trends and patterns.
  • Highlight possible areas for further investigation.
While useful for recognizing correlations, it is important to remember that observational studies cannot definitively establish cause-and-effect relationships.

plain the difference between the types of inference that can be made as a result of random sampling and random assignment.

An expert on worker performance is interested in the effect of room temperature on the performance of tasks requiring manual dexterity. She chooses temperatures of \(70^{\circ} \mathrm{F}\) and \(90^{\circ} \mathrm{F}\) as treatments. The response variable is the number of correct insertions, during a 30 -minute period, in a peg-and-hole apparatus that requires the use of both hands simultaneously. Each subject is trained on the apparatus and then asked to make as many insertions as possible in 30 minutes of continuous effort. (a) Describe a completely randomized design to compare dexterity at \(70^{\circ}\) and \(90^{\circ}\) using 20 volunteer subjects. (b) Because individuals differ greatly in dexterity, the wide variation in individual scores may hide the systematic effect of temperature unless there are many subjects in each group. Describe in detail the design of a matched pairs experiment in which each subject serves as his or her own control.

Researchers in Japan conducted an experiment on 13 individuals who were extremely allergic to poison ivy. On one arm, each subject was rubbed with a poison ivy leaf and told the leaf was harmless. On the other arm, each subject was rubbed with a harmless leaf and told it was poison ivy. All the subjects developed a rash on the arm where the harmless leaf was rubbed. Of the 13 subjects, 11 did not have any reaction to the real poison ivy leaf. \({ }^{40}\) Explain how the results of this study support the idea of a placebo effect.

Does day care help low-income children stay in school and hold good jobs later in life? The Carolina Abecedarian Project (the name suggests the \(\mathrm{ABC}\) s) has followed a group of 111 children since 1972. Back then, these individuals were all healthy but low-income black infants in Chapel Hill, North Carolina. All the infants received nutritional supplements and help from social workers. Half were also assigned at random to an intensive preschool program. \({ }^{36}\) Explain how each of the four principles of experimental design was used in this study.

At a party there are 30 students over age 21 and 20 students under age 21 . You choose at random 3 of those over 21 and scparately choose at random 2 of those under 21 to interview about attitudes toward alcohol. You have given every student at the party the same chance to be interviewed. Why is your sample not an SRS?
