Hypothesis Test for Test of Independence01:16

Hypothesis Test for Test of Independence

7.3K
The test of independence is a chi-square-based test used to determine whether two variables or factors are independent or dependent. This hypothesis test is used to examine the independence of the variables. One can construct two qualitative survey questions or experiments based on the variables in a contingency table. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses for this test are:
H0: The two variables (factors)...

Substance Use Disorders Affecting Sleep

344
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Introduction to Test of Independence

In statistics, the term independence means that one can directly obtain the probability of any event involving both variables by multiplying their individual probabilities. Tests of independence are chi-square tests involving the use of a contingency table of observed (data) values.
The test statistic for a test of independence is similar to that of a goodness-of-fit test:

CNS Depressants: Alcohol and Nicotine01:27

CNS Depressants: Alcohol and Nicotine

951
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Summary

Biracial Black youth alcohol use rates partially support the intermediate hypothesis, aligning more with non-Black groups. Black-American Indian youth show higher risks for problematic drinking.

Area of Science:

  • Sociology
  • Public Health
  • Psychology

Background:

  • The intermediate biracial substance use hypothesis posits that substance use among biracial individuals falls between that of their monoracial counterparts.
  • Understanding substance use patterns in biracial populations is crucial for targeted public health interventions.

Purpose of the Study:

  • To test the intermediate biracial substance use hypothesis using alcohol use trajectories.
  • To compare alcohol use patterns of biracial Black youth with their monoracial counterparts.

Main Methods:

  • Utilized data from the National Longitudinal Study of Adolescent and Adult Health (Add Health).
  • Analyzed a de-aggregated sample of 9,421 adolescents and young adults identifying as monoracial (Black, White, Hispanic, American Indian) or biracial Black (Black-American Indian, Black-Hispanic, Black-White).
  • Employed latent growth curve modeling to assess first use, number of drinks, and binge drinking.

Main Results:

  • Found partial support for the intermediate substance use hypothesis.
  • Alcohol use rates among biracial Black individuals more closely resembled their non-Black counterparts than monoracial Black individuals.
  • Biracial Black-American Indian youth exhibited a particularly high risk for problematic drinking.

Conclusions:

  • Findings highlight the complexity of substance use among biracial populations.
  • Emphasizes the need for further research into the onset and maintenance of alcohol use and misuse in biracial subgroups.
  • Suggests that interventions may need to be tailored to specific biracial identities.
