frequency distribution

  1. A curve the coordinates of which are the values of the variable and the frequency of occurrence. It is often presented as a histogram.


  2. (Also called frequency curve.) The relationship between the probability that a threshold is exceeded and the threshold.

    In a graphical representation, the curve is often plotted with frequency or probability on the vertical y axis and the corresponding rainfall or flood flow values on the horizontal x axis.
