Statistical Significance01:50

Statistical Significance

22.0K
Once data is collected from both the experimental and the control groups, a statistical analysis is conducted to find out if there are meaningful differences between the two groups. A statistical analysis determines how likely any difference found is due to chance (and thus not meaningful). In psychology, group differences are considered meaningful, or significant, if the odds that these differences occurred by chance alone are 5 percent or less. Stated another way, if we repeated this...

Probability in Statistics

23.5K
Probability is the likelihood of an event occurring. The term event is defined as a collection of results of a procedure. An event is a simple event when an outcome cannot be divided into simpler parts.
An example of a simple event is a coin toss. The result of a coin toss is either a head or a tail. Here, head and tail are two simple events. These two simple events make up the sample space. Further, the probability of an event occurring falls within the range of 0 to 1. The probability of an...

Design Consideration01:22

Design Consideration

582
Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.
The factor of safety is another key...

Introduction to Statistics

64.2K
The science of statistics involves collecting, analyzing, interpreting, and presenting data. The method of collecting, organizing, and summarizing data is called descriptive statistics. The systematic method of drawing inferences from the sample data and predicting unknown characteristics of a population is called inferential statistics.
In statistics, the collection of individuals or objects under study is called population. The idea of sampling is to select a portion of the larger population...

Overview of the Cardiovascular System01:14

Overview of the Cardiovascular System

12.0K
The cardiovascular system is a vital transportation system in the body. It comprises the heart and blood vessels and facilitates the exchange of gases, nutrients, and waste products.
Heart
The heart is the central pump of the cardiovascular system that circulates blood throughout the body. It comprises two atria receiving the blood and two ventricles pumping blood out of the heart. Their rhythmic contractions, called heartbeats, ensure that blood flow remains continuous.
Blood Vessels

Tensile Strength Considerations of Concrete01:16

Tensile Strength Considerations of Concrete

558
Considering the tensile strength of concrete involves recognizing that the theoretical strength of cement paste can be up to a thousand times higher than what is observed in practical applications. This significant discrepancy is largely attributed to the presence of microscopic cracks within the concrete. These cracks tend to amplify stress at their tips when a load is applied, a phenomenon explained by Griffith's theory of brittle fracture.
The dimensions and shape of a concrete specimen...

Area of Science:

  • Biomedical Literature Analysis
  • Cardiovascular Physiology Research

Background:

  • Inadequate statistical reporting is a persistent issue in biomedical literature, particularly in cardiovascular physiology.
  • Existing statistical reporting guidelines in clinical medicine do not specifically address cardiovascular physiology.

Purpose of the Study:

  • To assess the need for specific statistical reporting guidelines in cardiovascular physiology.
  • To determine the types and frequency of statistical tests used in the American Journal of Physiology-Heart and Circulatory Physiology.

Main Methods:

  • Conducted a PubMed search for articles published in the American Journal of Physiology-Heart and Circulatory Physiology from January 1, 2017, to October 6, 2017.
  • Evaluated 146 articles for statistical methods and conducted an in-depth analysis of 38 articles.

Main Results:

  • The t-test and ANOVA were the most common statistical tests, accounting for 71% of those performed.
  • Bonferroni and Tukey tests were frequently used post hoc tests (63%).
  • A general lack of detail in statistical reporting was observed.

Conclusions:

  • Developed recommended minimum reporting guidelines for statistical analysis in cardiovascular physiology manuscripts.
  • Implementing these guidelines can enhance the quality, rigor, and reproducibility of statistical reporting.
