What is the main difference between uncertainty and variability?
Uncertainty is derived from theoretical information, while variability is derived from data extracted from observations.
What are the sources of uncertainty classified into?
Aleatory uncertainty and epistemic uncertainty
When does variability occur?
When the quantity is measured at multiple instances and there are considerable differences between the measurement trials
What does aleatory uncertainty arise from?
Natural randomness
