Applied Statistics Workshop on Video

Over the course of the year we have tried to record many of the Applied Statistics workshop, but only now have we finally posted one. It is from Cassandra Wolos Pattanayak's talk on propensity score matching at the CDC from last week. You can find it here and on the seminar website.

ABSTRACT:
Although humans spend much of their time mind-wandering, i.e., thinking about something other than what one is actually doing, little is known about mind wandering's relation to human happiness. Using novel technology to achieve the world's largest experience sampling study of people's everyday lives, we found that participants spent nearly half of their waking hours mind-wandering and that it had large effects on happiness. Mind wandering was never observed to increase happiness and often reduced happiness considerably. Although some activities and situations modestly decreased the probability of mind wandering, they generally did not buffer against negative thoughts when a person's mind did stray from the present.
