What are interpolation of ogive curve?
An ogive is a cumulative relative frequency diagram. Interpolation is definiting the midpoint (50%) of this line
The graph of a cumulative frequency distribution is called?
ogive
Usefullness of ogive curve?
In statistics, the ogive curve is an approximation to the cumulative distribution function. It can be used to obtain various percentiles quickly as well as to derive the probability density function.
What is another name for cumulative frequency polygon?
It is called an ogive.
Does an ogive best represent the shape of a distribution?
While a two-dimensional ogive or a cross-section of a three-dimensional ogive may represent the shape of a given distribution, they are only good for representing higher-likelihood (one- and two-sigma) outcomes because ogives do not have characteristic low-likelihood tails tails. For very well managed processes (better than four sigma accuracy), a custom ogive may provide a very good approximation of resulting distribution.
