Outliers and Influential Points01:08

Outliers and Influential Points

4.8K
An outlier is an observation of data that does not fit the rest of the data. It is sometimes called an extreme value. When you graph an outlier, it will appear not to fit the pattern of the graph. Some outliers are due to mistakes (for example, writing down 50 instead of 500), while others may indicate that something unusual is happening. Outliers are present far from the least squares line in the vertical direction. They have large "errors," where the "error" or residual is the...

Data: Types and Distribution

937
In biostatistics, data are the observations collected for analysis. There are two main types: parametric and non-parametric. Parametric data, which include continuous (e.g., weight) and discrete numerical data (e.g., number of tablets), assume a particular distribution pattern, often the normal distribution. Non-parametric data do not adhere to a specific distribution and typically comprise nominal (e.g., gender) and ordinal categorical data (e.g., pain scale ratings).

Data Collection by Survey

7.5K
The systematic method of obtaining and analyzing accurate information of a population is called data collection. A survey is a standard method of data collection that involves collecting information from a target human population about their experience, opinion, or knowledge of a product, service, or process. The responses are recorded and interpreted. The most common survey examples are written questionnaires, face-to-face or telephonic conversations, focus groups, and electronic (e-mail or...

Data Collection by Observations

13.4K
Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
An astronomer viewing the motion and brightness of stars in the sky and recording the data is an example of observational data collection. A botanist recording...

Biostatistics: Overview01:20

Biostatistics: Overview

416
Biostatistics plays a crucial role in understanding and analyzing data in healthcare and biology. Biostatisticians conduct experiments, gather evidence, and draw meaningful conclusions using statistical methods and techniques. Different variables form the foundation of biostatistical analysis, allowing researchers to understand and interpret data effectively. These variables are classified into different types, each serving a specific purpose in statistical analysis.
Discrete variables are...

Statistical Analysis: Overview

10.1K
When we take repeated measurements on the same or replicated samples, we will observe inconsistencies in the magnitude. These inconsistencies are called errors. To categorize and characterize these results and their errors, the researcher can use statistical analysis to determine the quality of the measurements and/or suitability of the methods.
One of the most commonly used statistical quantifiers is the mean, which is the ratio between the sum of the numerical values of all results and the...

Area of Science:

  • Bibliometrics
  • Open Science
  • Data Science

Background:

  • Scientific portfolio analysis traditionally relies on citation data.
  • Limited transparency and accessibility of proprietary citation databases hinder robust analysis.
  • The growth of open-access initiatives has spurred the development of public-domain citation databases.

Purpose of the Study:

  • To highlight the impact of open citation data on scientific transparency and discoverability.
  • To analyze the recent growth and implications of public-domain citation databases.
  • To underscore the irreversible shift in the citation data ecosystem towards openness.

Main Methods:

  • Analysis of citation data growth trends.
  • Assessment of the impact of open citation data on scientific portfolio analysis.
  • Review of the scientific data ecosystem and the role of open data.

Main Results:

  • Public-domain citation databases surpassed one billion citations in February 2021.
  • The Crossref database alone now holds over one billion public-domain citations.
  • The diminishing advantage of closed databases signifies a fundamental change in data accessibility.

Conclusions:

  • Open citation data significantly improves scientific portfolio analysis and policy-making.
  • The proliferation of open citation data increases the discoverability of scientific articles.
  • The trend towards open citation data represents an irreversible and positive evolution in scientific information sharing.
