Causality is meant to move in one direction: forward. But the Quantum Eraser experiment seems to reverse causality. How and why can this happen and what are the implications of this experiment on how we understand Quantum Mechanics and...

You've discovered a habitable exoplanet, but so has an an evil interplanetary mining corporation. Can you get to the planet before they strip it bare and leave it unsuitable for life? You're going to need a ship, the Lorentz...

Find out how time and space switch roles when we move beyond the event horizon of the black hole.

This episode of Space Time is actually about Spacetime, so pull up a chair, grab your favorite snack, and buckle up, because this episode is going to be a TRIP. Gabe explores what reality is, what "time" is, and why what you think those...

This video is about how causal models (which use causal networks) allow us to infer causation from correlation, proving the common refrain not entirely accurate: statistics CAN be used to prove causality! Including:...

Summary:

If you point a powerful laser at the moon, and spin it 100 times per second, the dot on the moon will move 3X the speed of light. This is ok. The maximum speed limit is not a limit with which...

This video explains correlation versus regression.<br<br/>/>

This clip is from the chapter "Linear Regression Analysis" of the series "R Programming for Statistics and Data Science".This section explains linear regression analysis.

When I was a medical student, I remember doing a psych rotation on a pediatric ward. I was struck by how many of the admissions were for eating disorders. Even before then, I was aware that more than a small number of my female friends...

Malpractice is a complicated subject. Studies seem to indicate, however that there are some effective strategies for reducing the costs associated with medical errors.

Determining causality isn't easy. Correlation doesn't mean causation. And yet where we see a strong correlation between an exposure and an outcome, we need to be able to determine if there is a cause and effect relationship. Public...

Promising health studies often don’t pan out in reality. The reasons are many. Research participants are usually different from general patients; their treatment doesn’t match real-world practice; researchers can devote resources not...

This video explains the importance of not assuming causation based on correlation in statistical analysis. Through examples of shoe size and reading levels, as well as meditation and blood pressure, the teacher demonstrates how language...

In this video, the teacher explains the difference between correlation and causation by discussing the role of linking and lurking variables. They provide examples to illustrate how two variables can be correlated without one causing the...

In this video, you will learn about correlation and regression.

This film uses some famous psychological experiments (such as Bandura's BoBo doll and Loftus's Eyewitness Testimony) to show, rather than simply tell, students: what is meant by the experimental method in psychology, how laboratory...
