Description

Time in darkness for mice in different environments

Format

A dataset with 14 observations on the following 2 variables.

Time Time spent in darkness (in seconds)
Environment Type of environment: Enriched or Standard

Details

In the recent study, mice were randomly assigned to either an enriched environment where there was an exercise wheel available, or a standard environment with no exercise options. After three weeks in the specified environment, for five minutes a day for two weeks, the mice were each exposed to a "mouse bully" - a mouse who was very strong, aggressive, and territorial. one measure of mouse anxiety is amount of time hiding in a dark compartment, with mice who are more anxious spending more time in darkness. The amount of time spent in darkness is recorded for each of the mice.
