Fat Mice 18


Weight gain for mice with different nighttime light conditions


A dataset with 18 observations on the following 2 variables.

  • Light Light treatment: LD= normal light/dark cycle or LL=bright light at night

  • WgtGain4 Weight gain (grams over a four week period)


This is a subset of the LightatNight dataset, showing body mass gain in mice after 4 weeks for two of the treatment conditions: a normal light/dark cycle (LD) or a bright light on at night (LL).
