A Note about the Fossa Certificate
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) |

The mouse data set is not opening
The data sets aren’t opening
Hello Oluwatosin. The datasets seem to be working for me. Can you share a screenshot of where you are running into issues?
The mouse data set and fossa data sets seem not to open
I am unable to download either of the two files.
Hi Minh. The datasets should now be back up. Please try again and let us know if you run into more issues.
Thanks for the update! I successfully downloaded the two files. I appreciate your help. I’ll let you know if I run into any issues.
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.
This should be fixed now!
