Words number of words recalled
These data were used in a "resampling bake-off" hosted by Robin Lock.
In an experiment on memory (Mednicj et al, 2008), students were given lists of 24 words to memorize. After hearing the words they were assigned at random to different groups. One group of 12 students took a nap for 1.5 hours while a second group of 12 students stayed awake and was given a caffeine pill. The data set records the number of words each participant was able to recall after the break.
