Hypothesis Test for Test of Independence01:16

Hypothesis Test for Test of Independence

5.5K
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)...

Depressants01:28

Depressants

227
Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

253
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,...

Introduction to Test of Independence

2.6K
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

612
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...

Self-Presentation: Self-Monitoring and Self-Handicapping

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
This summary is machine-generated.

Rideshare services in Houston significantly reduced motor vehicle crashes (MVCs) and impaired driving convictions. Increased rideshare use is linked to fewer traffic traumas and DUI offenses.

Area of Science:

  • Public Health
  • Transportation Safety
  • Epidemiology

Background:

  • Motor vehicle crashes (MVCs) pose a significant public health risk.
  • Emerging data suggests rideshare services may reduce MVC incidence, but conclusive evidence linking rideshare volume, impaired driving, and trauma rates is lacking.

Purpose of the Study:

  • To investigate the association between rideshare utilization and MVC traumas.
  • To determine the relationship between rideshare use and impaired driving convictions in Houston, Texas.

Main Methods:

  • A multicenter cohort study analyzed hospital data from January 2007 to November 2019.
  • Rideshare data (Uber) and impaired driving conviction records were collected for Houston, Texas.
  • Incident rate ratios for hourly MVC traumas and daily impaired driving convictions were calculated.

Main Results:

  • Following Uber's introduction, MVC traumas decreased by 23.8% during peak hours (IRR, 0.33 per 1000 rides; P=.002).
  • Rideshare use correlated with a significant reduction in impaired driving convictions (IRR, 0.76; P<.001).
  • Over 23,000 MVC traumas and 93,000 impaired driving convictions were analyzed.

Conclusions:

  • Rideshare services in Houston are associated with substantial decreases in MVC traumas.
  • Increased rideshare adoption appears effective in reducing both impaired driving and MVC-related injuries.
  • Findings highlight the potential of rideshares as a public health intervention for traffic safety.
