Abstract: An important official knowledge in each country is to
have a comprehensive knowledge about markets of each group of
products. Drink markets are one the most important markets of each
country as a sub-group of nourishment markets. This paper is going
to study these markets in Iran. To do so, first, two drink products are
selected as pilot, including milk and concentrate. Then, for each
product, two groups of information are estimated for the last five
years, including 1) total consumption (demand) and 2) total
production. Finally, the two groups of productions are compared
statistically by means of two statistical tests called t test and Mann-
Whitney test. The implemented Different related tables and figures
are also illustrated to show the method more explicitly.
