概括
一个新的多维农村指数揭示了美国各州的不同农村形象,改善了卫生政策研究,超出了人口百分比等单一指标. 这个工具有助于有针对性的比较,以便更好地分配资源.
科学领域:
- 农村卫生政策 农村卫生政策
- 地理健康差异的差异
- 社会人口统计学指标
背景情况:
- 目前的州级农村化措施,通常是单个指标,如人口百分比或人口密度,不足以进行全面分析.
- 这些简单的措施掩盖了国家之间的关键差异,导致卫生政策研究和资源配置的过度概括.
- 多维方法对于准确地描述农村和为医疗保健获取,质量和公平性提供研究信息至关重要.
研究的目的:
- 为所有50个美国州制定一个复合的,多维的农村指数.
- 创建一个更细致的排名系统,超越单一指标的限制.
- 为提供一个工具,以便在政策和研究方面更准确地比较农村国家.
主要方法:
- 开发了一个综合指数,使用三个关键指标:农村人口百分比,农村土地面积百分比和农村人口密度.
- 使用Borda数和统治数排名方法来整合这些指标.
- 利用主要组件分析 (PCA) 来实现数据可视化和识别具有相似农村特征的州.
主要成果:
- 山西州 (如阿拉斯加,蒙大拿,怀俄明) 在多维农村指数上排名最高.
- 像佛蒙特州和缅因州这样的州,通常仅仅根据人口份额被认为是农村地区,表现出与传统较少的农村州 (例如,密西西比州,阿肯色州) 类似的概况.
- PCA区分了基于土地的农村 (广,人口稀少的地区) 和基于人口的农村 (农村城镇居民的比例很高).
结论:
- 与单个指标相比,开发的多维农村指数为卫生政策研究提供了优越的工具.
- 它可以在不同农村国家之间进行更有针对性和有意义的比较.
- 该指数可以通过承认农村的多样性来指导研究农村医疗保健基础设施,劳动力挑战和健康公平.

Ranks

Unlike parametric methods, nonparametric statistics are ideal for nominal and ordinal data, requiring fewer assumptions about the population's nature or distribution. This makes nonparametric methods easier to apply and interpret, as they do not depend on parameters like mean or standard deviation. One common approach in nonparametric analysis is to sort data according to a specific criterion. For instance, we might arrange weather data from hottest to coldest days in a month or rank cities...

Ordinal Level of Measurement
31.8K
The way a set of data is measured is called its level of measurement. Correct statistical procedures depend on a researcher being familiar with levels of measurement. For analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
Data measured using an ordinal scale are similar to nominal scale data, but there is one major difference. The ordinal scale data can be ordered. An example of ordinal scale data is a list of the top five national parks...

Levels of Use of a GIS
313
Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...

Friedman Two-way Analysis of Variance by Ranks
465
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...

Review and Preview
8.3K
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.

Selected Data About Geographic Locations
243
Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...
