Histograms frequency density
WebbYes. It tells you how often (frequency) your data fall into each bin. I can't say whether that's what you're looking for or not. You could plot a normalized histogram where all the bars hights add to 1.0. You could normalize the histrogram so the tallest bar is always equal to 1. You could plot the underlying density function. WebbIn a Relative Frequency Density Histogram Area = relative frequency Given a set of n data points, if an interval contains f of the data points, and the width of the interval is ∆x, Then the relative frequency density(rfd) is defined by ∆x*(rfd) = f/n, the relative frequency The rfd is the height of the rectangle.
