Methods to Assess Microbial Communities01:19

Methods to Assess Microbial Communities

37
Microbial communities, comprising bacteria, archaea, and eukaryotic microorganisms, inhabit diverse ecosystems and play crucial roles in environmental and biological processes. Their diversity is defined by three main parameters: species richness (the number of distinct species), species abundance (the relative quantity of each species), and species evenness (how uniformly individual species are distributed in various locations). These factors together shape the structure and ecological balance...

Ordinal Level of Measurement00:55

Ordinal Level of Measurement

37.6K
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...

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.
Percentiles are a type of fractile that partition data into...

Central Tendency: Analysis01:10

Central Tendency: Analysis

638
Measures of central tendency are tools used in biostatistics to identify the average or center of a dataset. They offer a single representative value for understanding and summarizing data distribution.
The mean is one such measure, calculated by totaling all values in a dataset and dividing by the number of values. For instance, the mean blood pressure reading (120, 130, 140, 150) would be 135. However, the mean can be affected by extreme values or outliers.
The median, another measure,...

Ratio Level of Measurement

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.
A set of data measured using the ratio scale takes care of the ratio problem and provides complete information. Ratio scale data are like interval scale data, except they have a zero point and ratios can be calculated....

Introduction to Nonparametric Statistics01:28

Introduction to Nonparametric Statistics

1.7K
Nonparametric statistics offer a powerful alternative to traditional parametric methods, useful when assumptions about the population distribution cannot be made. Unlike parametric tests, which require data to follow a specific distribution with well-defined parameters (such as the mean and standard deviation), nonparametric tests do not require such constraints. This makes them particularly valuable when dealing with small sample sizes, skewed data, or ordinal and categorical variables.
One of...

Summary

Article-level metrics complement traditional journal metrics by aggregating diverse data sources like usage and social media mentions. Altmetrics offer real-time insights into scholarly impact beyond citations.

Area of Science:

  • Bibliometrics
  • Scholarly Communication
  • Information Science

Background:

  • Traditional metrics focus on journal-level citations.
  • Emerging article-level metrics (ALM) offer a more comprehensive view of research impact.
  • Altmetrics provide real-time insights into the social impact of scholarly outputs.

Purpose of the Study:

  • To define and differentiate altmetrics from traditional metrics.
  • To explore the aggregation of diverse data sources for article-level metrics.
  • To overview existing tools for applying altmetrics.

Main Methods:

  • Aggregation of data from multiple sources: usage, captures, mentions, social media, and citations.
  • Inclusion of data from academic social networks (Mendeley, CiteULike) and general social media (Facebook, Twitter, blogs).
Keywords:

  • Review of tools such as PLOS-ALM, Altmetric, Impactstory, and PlumX.

    • Main Results:

    • Article-level metrics complement, rather than replace, traditional journal metrics.
    • Altmetrics provide early availability and assess social impact in near real-time.
    • Diverse data sources offer a richer picture of article utilization.

    Conclusions:

    • Article-level metrics and altmetrics enhance the understanding of research impact.
    • Combining traditional and article-level metrics provides a more holistic assessment.
    • The described tools facilitate the application of these emerging metrics.
