Abstract: This paper illustrates with an example comparison of the geometrical and the numerical approaches of measures of location. A geometrical derivation of the most popular measure of location (mean) was derived from histogram by determining its (histogram) centroid. The numerical or mathematical expression of the other measures of location, median and mode were derived from ogive and histogram, respectively. Finally, the research establishes that the two approaches produce the same results.
