An ogive is a curve that represents cumulative frequencies of the given variables. The graph of the cumulative frequency distribution is better known as the cumulative frequency curve or Ogive.The word Ogive is basically a term used in the architecture to describe curves or curved shapes.et us go ahead and understand about the cumulative frequency curve in this page. The cumulative frequency curve is also known as Ogive. Just to recall that the cumulative frequency of a variable is the summation of all the frequencies of variables previous to it.
