Hypothesis Test for Test of Independence01:16

Hypothesis Test for Test of Independence

6.2K
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)...

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:

Deindividuation00:57

Deindividuation

29.6K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

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...

Determination of Expected Frequency

2.4K
Suppose one wants to test independence between the two variables of a contingency table. The values in the table constitute the observed frequencies of the dataset. But how does one determine the expected frequency of the dataset? One of the important assumptions is that the two variables are independent, which means the variables do not influence each other. For independent variables, the statistical probability of any event involving both variables is calculated by multiplying the individual...

CNS Depressants: Alcohol and Nicotine

781
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...

Summary

Subjective intoxication (SI) and risky single-occasion drinking (RSOD) measures for harmful alcohol use were compared. RSOD is a more reliable indicator of harmful drinking patterns than SI, despite SI offering insights into perceptions.

Area of Science:

  • Public Health
  • Epidemiology
  • Alcohol Research

Background:

  • Harmful drinking is often measured by risky single-occasion drinking (RSOD) quantity thresholds.
  • Subjective intoxication (SI) offers alternative insights into alcohol perception and cultural factors.
  • Limited research exists comparing RSOD and SI measures for harmful drinking.

Purpose of the Study:

  • To compare the prevalence and correlation of subjective intoxication (SI) and risky single-occasion drinking (RSOD) measures.
  • To investigate factors influencing the relationship between SI and RSOD.
  • To determine the utility of SI as an indicator of harmful drinking compared to RSOD.

Main Methods:

  • Analysis of data from the 2015 Standardized European Alcohol Survey (N=25,028).
  • Calculation and comparison of survey-weighted prevalence of SI and RSOD using correlation and regression models.
  • Examination of alcohol quantity for perceived impairment, demographics, and drinking patterns.

Main Results:

  • SI prevalence was generally lower than or equal to RSOD prevalence across most locations.
  • SI and RSOD prevalence estimates demonstrated a high correlation.
  • The quantity of alcohol needed for perceived impairment explained approximately 8% of the variance in the SI-RSOD difference.

Conclusions:

  • Subjective intoxication (SI) is not a preferable indicator of harmful drinking compared to conventional risky single-occasion drinking (RSOD) measures.
  • Individual perceptions of impairment are influenced by alcohol quantity but less so by sociodemographic factors.
  • RSOD remains a more conventional and potentially more reliable measure for epidemiological studies of harmful drinking.
