Reliability and Validity01:29

Reliability and Validity

12.8K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Bonferroni Test01:10

Bonferroni Test

2.8K
The Bonferroni test is a statistical test named after Carlo Emilio Bonferroni, an Italian mathematician best known for Bonferroni inequalities. This statistical test is a type of multiple comparison test to determine which means are different than the rest. Bonferroni test can minimize the Type 1 error by reducing the significance level alpha, which otherwise increases with sample pairs.
The means of different samples are first paired in all possible combinations.
The null hypothesis of the...

Friedman Two-way Analysis of Variance by Ranks01:21

Friedman Two-way Analysis of Variance by Ranks

264
Friedman's Two-Way Analysis of Variance by Ranks is a nonparametric test designed to identify differences across multiple test attempts when traditional assumptions of normality and equal variances do not apply. Unlike conventional ANOVA, which requires normally distributed data with equal variances, Friedman's test is ideal for ordinal or non-normally distributed data, making it particularly useful for analyzing dependent samples, such as matched subjects over time or repeated measures...

Testing a Claim about Population Proportion01:24

Testing a Claim about Population Proportion

3.4K
A complete procedure for testing a claim about a population proportion is provided here.
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...

Surveys02:16

Surveys

14.9K
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.

Bias01:22

Bias

4.3K
Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

Area of Science:

  • Public Health
  • Epidemiology
  • Infectious Diseases

Background:

  • The COVID-19 pandemic has led to widespread infections, including among essential healthcare workers.
  • Understanding infection dynamics in healthcare settings is crucial as the pandemic transitions to an endemic phase.

Purpose of the Study:

  • To determine the period prevalence of COVID-19 among paediatric healthcare workers in Negeri Sembilan.
  • To investigate sociodemographic and occupational factors associated with SARS-CoV-2 infection in this population.

Main Methods:

  • A cross-sectional study was conducted among paediatric healthcare workers in three public hospitals in Negeri Sembilan.
  • Data were collected via a self-administered questionnaire between April 15-21, 2022.

Main Results:

  • The overall COVID-19 prevalence was 50.9%, with 80.1% of infections occurring during the Omicron wave.
  • Household contacts were the primary source of infection (35.9%).
  • Infected workers were more likely to be non-doctors and have school-going or preschool-aged children.

Conclusions:

  • The study quantifies COVID-19 prevalence and associated factors among paediatric healthcare workers in Negeri Sembilan.
  • Household transmission and the presence of young children in the household are significant risk factors for infection in this group.
