Frequency Curve Example. Frequency curve The procedure for drawing a frequency curve is same as for frequency polygon. To plot a frequency curve without using histogram we need to plot the frequency of the class against its class marks and join the points with line segments.
It is a free-hand graph showing the curve of a cumulative frequency. May 09 2017 A frequency polygon is a type of line graph that shows the frequency of a mutually exclusive event occurring. By joining the points the curve so obtained is called a cumulative frequency curve or ogive.
Frequency curve The procedure for drawing a frequency curve is same as for frequency polygon.
Frequency curves have many uses in hydrol- ogy. If both less than and greater than cumulative frequency curve is drawn on the same graph we can easily find the median value.
