A new study uses an analytical technique called 'network science' to determine factors contributing to statistics anxiety among psychology majors.
Dr. Teruyoshi Kobayashi of Kobe University and his team developed a new method for identifying individuals that have essential connections between them -- what they call 'significant ties'. Dr. Kobayashi says: "The point is that we need to distinguish between the contact events that could happen by chance and the events that would not happen without a significant relationship between two individuals." Their findings were published in Nature Communications on January 15.
MIT researchers are hoping to advance the democratization of data science with a new tool for nonstatisticians that automatically generates models for analyzing raw data.
People make statistically-informed judgments about who is more likely to hold particular professions even though they criticize others for the same behavior, according to findings published in Psychological Science, a journal of the Association for Psychological Science.
In a paper published Jan. 2 in PLOS Biology, two scientists at the University of Washington and North Carolina State University use the economic theory of contests to illustrate how the competitive grant-application system has made the pursuit of research funding inefficient and unsustainable -- and that alternative methods, such as a partial lottery to award grants, could relieve pressure on professors and free up time for research.
Measuring the knowledge of students in online courses poses a number of challenges. Researchers from the Higher School of Economics and the University of Leuven made improvements to the model for assessing academic achievements and published their results in the journal Heliyon.
Two University of Washington scientists have unveiled a new statistical method for estimating migration flows between countries. Using the so-called pseudo-Bayes approach, they show that rates of migration are higher than previously thought, but also relatively stable, fluctuating between 1.1 and 1.3 percent of global population from 1990 to 2015. In addition, since 1990 approximately 45 percent of migrants have returned to their home countries, a much higher estimate than other methods.
Human error, not human biology, largely accounts for the apparent decline of mortality among the very old, according to a new report publishing on Dec. 20, 2018, in the open-access journal PLOS Biology by Saul Newman of Australia National University in Canberra. The result casts doubt on the hypothesis that human longevity can be greatly extended beyond current limits.
Machine-learning research published in two related papers today in Nature Geosciences reports the detection of seismic signals accurately predicting the Cascadia fault's slow slippage, a type of failure observed to precede large earthquakes in other subduction zones.
The research has proven that pupils who engage in puzzle solving consistently show higher aptitude in IQ tests. As a s result, a number of recommendations appeared considering the inclusion of puzzles into various types of teaching activities. They can potentially boost logical and abstract thinking, combinatorial and spatial skills, and mathematical memory.
