Normal density curves 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 ... WebA normal distribution curve is plotted along a horizontal axis labeled, Trunk Diameter in centimeters, which ranges from 60 to 240 in increments of 30. The curve rises from the horizontal axis at 60 with increasing steepness to its peak at 150, before falling with …
