When performing a two-sample t procedure, the degrees of freedom can be determined by taking the smaller of the two samples and subtracting 1. This is known as the conservative approach and ensures that the degrees of freedom do not exceed the true value. Taking the larger sample or adding 1 to the smaller sample will give a larger degrees of freedom, which can lead to an inflated estimate of the standard error and a wider confidence interval.
