Distributions to Estimate Population Parameter01:26

Distributions to Estimate Population Parameter

5.0K
The accurate values of population parameters such as population proportion, population mean, and population standard deviation (or variance) are usually unknown. These are fixed values that can only be estimated from the data collected from the samples. The estimates of each of these parameters are sample proportion, the sample mean, and sample standard deviation (or variance). To obtain the values of these sample statistics, data are required that have particular distribution and central...

Finding Critical Values for Chi-Square

4.2K
Consider a curve representing sample data drawn randomly from a normally distributed population. One must construct confidence intervals to estimate or to test a claim regarding the population standard deviation. For example, a 95% confidence interval covers 95% of the area under the curve, and the remaining 5% is equally distributed on either side of the curve. To achieve such confidence intervals, one must determine the critical values. The critical values are simply the values separating the...

Percentile

8.4K
A percentile indicates the relative standing of a data value when data are sorted into numerical order from smallest to largest. It represents the percentages of data values that are less than or equal to the pth percentile. For example, 15% of data values are less than or equal to the 15th percentile.

Estimating Population Standard Deviation01:26

Estimating Population Standard Deviation

3.3K
When the population standard deviation is unknown and the sample size is large, the sample standard deviation s is commonly used as a point estimate of σ. However, it can sometimes under or overestimate the population standard deviation. To overcome this drawback, confidence intervals are determined to estimate population parameters and eliminate any calculation bias accurately. However, this only applies to random samples from normally distributed populations. Knowing the sample mean and...

Estimating Population Mean with Unknown Standard Deviation

8.7K
In practice, we rarely know the population standard deviation. In the past, when the sample size was large, this did not present a problem to statisticians. They used the sample standard deviation s as an estimate for σ and proceeded as before to calculate a confidence interval with close enough results. However, statisticians ran into problems when the sample size was small. A small sample size caused inaccuracies in the confidence interval.

Applications of Life Tables01:22

Applications of Life Tables

311
Life tables are versatile across various fields, providing a quantitative basis for analyzing mortality and survival rates. Whether used by demographers, actuaries, epidemiologists, or sociologists, life tables offer valuable insights into the dynamics of life and death, facilitating informed decisions in public health, insurance, conservation, and beyond. Their broad applicability highlights the interconnectedness of demographic data with practical outcomes in everyday life and strategic...

Summary

This study provides updated health-related quality of life (HRQoL) data for Vietnam. Older age, unemployment, low education, and chronic diseases significantly impact HRQoL in the Vietnamese population.

Area of Science:

  • Health Economics
  • Public Health
  • Epidemiology

Background:

  • Health-related quality of life (HRQoL) is crucial for population health assessment.
  • Updated HRQoL data specific to the Vietnamese population is needed for accurate health economic evaluations.
  • The EQ-5D-5L instrument is a widely used tool for measuring HRQoL.

Purpose of the Study:

  • To update health-related quality of life (HRQoL) data in the Vietnamese population using the EQ-5D-5L instrument.
  • To identify sociodemographic and health-related factors associated with HRQoL in Vietnam.
  • To provide current data for healthcare planning and health economic evaluations in Vietnam.

Main Methods:

  • A cross-sectional online survey was conducted with 3550 Vietnamese adults (aged 18+).
  • Participants were recruited via convenience and snowball sampling through online platforms.
  • HRQoL was measured using the EQ-5D-5L index and EQ-VAS, with data analyzed using descriptive statistics and multivariable Tobit regressions.

Main Results:

  • The mean EQ-5D-5L index score was 0.896 and the mean EQ-VAS score was 86.7.
  • Significant differences in HRQoL were observed across age groups, employment status, education levels, and chronic disease presence (p < 0.001).
  • Older age, unemployment, lower education, and multiple morbidities were independently associated with lower HRQoL.

Conclusions:

  • The study provides updated HRQoL data for Vietnam, highlighting the influence of age, socioeconomic status, and health conditions.
  • Findings confirm that sociodemographic factors and health status significantly impact HRQoL in the Vietnamese population.
  • The results are valuable for informing healthcare planning, health economic evaluations, and public health interventions in Vietnam.
