Momentlerin Sayısal Hesabı
Abstract
A good correction procedure is given by Sheppard's corrections that are nowadays still employed. Sheppard's
corrections are usually referred to continuous parent distribution. But grouping includes also censoring or splitting
data into categories during collection or publication, and so it does not only involve continuous variables. The
grouping of the data cause rounding errors. Rounding errors cause biases in the result obtained. When moments
are calculated from a numerically specified distribution which grouped, there is present a certain amount of
approximations owing to the fact that the frequencies are assumed to be concentrated at the mid-points of intervals.
Naturally, there are some mistakes that arises from assumptions. The purpose of this work is to correct for this
effect under certain conditions.
