Sampling theory and practice

In today's society particularly in the business world administrators sales strategy managers or decision-makers increasingly require the market for both supply and demand.Thus in recent years marketing has made a leap in updating its instruments to be at the forefront of the markets not only to offer its products but also to measure the consumption capacity of demanders.On the supply side what and where should I sell? How much should I produce? Who is my product aimed at? How can I know which socioeconomic group prefers my product?These and many other questions can be solved by the sampling technique which is an instrument of statistics to obtain sample indicators that will allow us to estimate the parameters or behavior of all consumers.That is the objective of this book: to develop the theoretical aspects in a summarized form and to develop some practical examples that will serve as a guide to all readers when analyzing the market of their products.
