Summary
Classical inequality measures are one-sided. This study introduces new indicators that simultaneously measure both attainment and shortfall inequality, offering a more comprehensive view of distribution disparities.
Area of Science:
- Economics
- Statistics
- Social Sciences
Background:
- Traditional inequality measures often focus solely on attainment or shortfall.
- This one-sided approach can limit a complete understanding of distribution disparities.
Purpose of the Study:
- To develop novel inequality indicators that capture both attainment and shortfall.
- To extend existing inequality measurement frameworks.
Main Methods:
- Derivation of new inequality indicators.
- Integration into the Gini family and Coefficient of Variation family.
- Analysis of connections to other established inequality measures.
Main Results:
- Successful derivation of two new inequality indicators.
- Demonstration of their ability to simultaneously assess attainment and shortfall.
- Established links between these novel indicators and existing measures.
Conclusions:
- The proposed indicators offer a more holistic assessment of inequality.
- These measures provide a richer understanding of distribution dynamics beyond one-sided perspectives.

01:20Sign Test for Median of Single Population
In general, the sign test serves as a nonparametric method to test hypotheses about the median of a single population when the data does not follow a known distribution. This simplicity makes it particularly useful for small sample sizes or when the assumptions of parametric tests cannot be met. The process begins with identifying a null hypothesis, typically stating that the population median equals a specific value. The alternative hypothesis could be that the median is either not equal to,...
01:28Inequalities
Inequalities express mathematical relationships where two values are not equal and are compared using symbols such as <, >, ≤, or ≥. These expressions define a range of possible solutions rather than a single value. Interval notation provides a concise way to express these solution sets, especially when the variable spans a continuous range. An open interval, written as (a, b), excludes the endpoints, while a closed interval [a, b] includes them. There are also half-open intervals, such...
01:15One-Way ANOVA: Unequal Sample Sizes
One-way ANOVA can be performed on three or more samples of unequal sizes. However, calculations get complicated when sample sizes are not always the same. So, while performing ANOVA with unequal samples size, the following equation is used:
01:15One-Way ANOVA: Equal Sample Sizes
One-Way ANOVA can be performed on three or more samples with equal or unequal sample sizes. When one-way ANOVA is performed on two datasets with samples of equal sizes, it can be easily observed that the computed F statistic is highly sensitive to the sample mean.
Different sample means can result in different values for the variance estimate: variance between samples. This is because the variance between samples is calculated as the product of the sample size and the variance between the...

01:10Review and Preview
In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

01:29Application of Nonlinear Inequalities
A nonlinear inequality describes a comparison involving an expression that curves or behaves more complexly than a straight line. These inequalities often appear in forms that include squares, products, or variables in the denominator.To solve such an inequality, one starts by rewriting it so that zero appears on one side. For example, the inequality: can be factored as: This form makes it easier to identify the values that cause the expression to equal zero. In this case, the key values are 3...
