We recently took a guided tour of statistical significance, in which we focused on how the media often fails to correctly interpret statistical information. But, journalists are not the only group that is tripped up by statistics. The scientific community itself has been engaged in deep debate about the proper use of statistical methodology. These debates… Read more »

The perils of publish or perish
Academia is a tough career choice. The pay is low (especially for graduate students), the hours are long, and the job market is uncertain. Those entering the field often receive this simple advice — “publish or perish.” Publications are the central method by which people are evaluated in academia. One either continually publishes papers, ideally… Read more »
A skeptic’s guide to statistical significance
“There’s no safe amount of alcohol,” CNN reported. This year the largest ever study on the health risks of alcohol was released, attracting mass media attention and igniting a science journalism furor over its interpretation. In the study, researchers found a significant increased in risk of death for individuals who consume even one drink a day…. Read more »
Groundhog Day 2018: Probability in perspective
This Friday will be the 132nd official Groundhog Day in the United States. Celebrated in Canada, Germany, and the U.S., the holiday derives from a long-standing German-Dutch tradition, which we’ve been officially recording since 1886. The basic idea: if a groundhog emerges from his hole and sees his shadow, winter will last for six more… Read more »
How researchers use sequencing techniques for social science research
Have you ever wondered why or how researchers categorize people into different groups? Of course, there are specific types of groups you might first think of, such as differentiating people by race, gender, income level, marital status, and education. However, there are a variety of other types of groups that researchers might find interesting that… Read more »
What is change??
What is “change”? This might at first seem like an oddly philosophical question to encounter in a science blog. The Greek philosopher Heraclitus once described change as the idea that “One cannot step into the same river twice” (paraphrased; Graham 2015). However, this more existential definition for change differs in important ways from the one… Read more »
Biological Venn diagrams: Where do math and biology intersect?
Think back to some of the core materials you learned from a biology course, either in college or high school. What do you remember? Maybe you remember something about human anatomy, or the carbon cycle, the structure of cells, or how DNA is replicated? But do you ever immediately think about how math and biology… Read more »
