COMP 5340/6340 Continuous Random Variables 2 Preamble Continuous probability distribution are not related to specific “experiments” There are multiple “shapes” (with parameters) that fulfill the probability distribution condition (area under shape equal to one. In general, you plot your sample data and try to find a shape that fits sample data.
