The data file can be downloaded here:
Data from an experiment to study the effects of preserving liquids on the enzyme content of dog hearts (Payne et al. 2022). There were 23 hearts (heart) and 2 treatment factors (A and B), each at two levels. Measurements were made as a percentage of total enzyme in the heart (ATP), at 1 and 2 hourly intervals (time) during a 12-hour period following initial preservation.
| heart | time | A | B | ATP |
