Density statistics definition
WebIn probability theory, a probability density function ( PDF ), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would be ...

For example, to answer my original question, the probability that a randomly chosen session will last between 25 and 35 minutes can be calculated as the area between the density function (graph) and the x-axis in the interval [25, 35]. This area equals 0.318.
