Baseline FHR Variability. Baseline variability is defined as fluctuations in the fetal heart rate of more than 2 cycles per minute. No distinction is made between short-term variability (or beat-to-beat variability or R-R wave period differences in the electrocardiogram) and long-term variability.
Variance. Variance is a measurable change from a known standard or baseline. In other words, variance is the difference between what is expected and what is actually accomplished. In project management, variance baseline is established by identifying the cost, schedule and scope. Scope defines all the work which needs to be done.
