The FoSSA Mouse dataset is a simulated set of health check data of a group of 60 mice throughout a fictional study. The data consist of weights in grams and body condition scores on a 5 point ordinal scale, each taken at three points throughout the trial. 

Weights are quite self explanatory, but if you would like a frame of reference for the body condition scores (BCS) then you can see how these are assigned here- Body Condition Score Mice.pdf 

Variable name Description Type of measure Coding
Strain Names of the three strains of mice in the trial, use for reference purposes Categorical Names
Strain_group Numerical groupings of the three mouse strains Categorical

1= Wild type, 2= Cdkn1a knockout, 3= NRAS knockout

Weight_baseline Weight measured at the beginning of the study Continuous Value in grams 
BCS_baseline Body condition score assessed at the beginning of the study Ordinal 1= lowest body condition (very underweight), 5= highest body condition (obese) 
Weight_mid Weight measured at the mid point of the study Continuous Value in grams 
BCS_mid Body condition score assessed at the mid point of the study Ordinal 1= lowest body condition (very underweight), 5= highest body condition (obese) 
Weight_end Weight measured at the end of the study Continuous Value in grams 
BCS_end Body condition score assessed at the end of the study Ordinal 1= lowest body condition (very underweight), 5= highest body condition (obese)

In this Course dataset
I learned about body condition score of mice, how to tell if it’s underweight or overweight without any form of invasion.
I must admit that it is very insightful and interesting

Hello, could you please see the data set above. When you click the data set 1 is opening in place of mouse data set.
