The rate of lactic acid turnover was measured by two methods for normal and diabetic dogs.
A data frame with 20 observations on the following 4 variables.
DogCode for individual dogs (d1 through d10)
MethodTracer method to measure response (infuse or inject)
OperationPancreas removed to make the dog diabetic? (no or yes)
ResponseRate for biochemical turnover of lactic acid
Five dogs had their pancreas removed to make them diabetic (Operation=yes), the other five were normal (Operation=no). The rate of turnover of lactic acid was measured for each dog by two methods, infusion and injection.
