Charts for each category, other than "Monograph Prices by Language," include the following data: the number of items in the category (Items); the total price of the items (Total); and the arithmetic mean of the total (Mean).

as simple arithmetic mean of mobile averages, if the intervals between the moments are equal: [[bar.

To make the data analysis statistically sound, various statistical techniques such as percentage, arithmetic mean and weighted arithmetic mean have been used.

n]), (2) where H and A stands for Harmonic mean and Arithmetic mean respectively.

Hartley Hyde takes us on a geometric tour in his latest Cactus column, investigating the link between the arithmetic mean, the geometric mean and the harmonic mean while introducing Geometric Expressions.

These include arithmetic mean, the median and the mode.

We recall some of the well-known means for a, b > 0, in the following table: Name Notation Definition Arithmetic Mean A(a, b) [a + b]/2 Geometric mean G(a, b) [square root of [ab]] Harmonic Mean H(a, b) [2ab]/[a + b] Logarithmic Mean L(a, b) [[a - b]/[In a - In b]] when a [not equal to] b a when a [not equal to] b Heron Mean [H.
