Many people find statistics challenging, but most statistics professors do not.
As a result, it is sometimes hard for our professors and the authors of statistics
textbooks to make statistics clear and practical for business students,
managers, and executives. Business Statistics Demystified fills that gap. We
begin slowly, introducing statistical concepts without mathematics.
In Business Statistics, we try to narrow the gap between theory and practice by presentingstatistical methods so they are both relevant and interesting.The data that inform a business decision have a story to tell, and the role ofStatistics is to help us hear that story clearly and communicate it to others.

A: Basically, statistics is the “science of data.” There are three main tasks in statistics: (A)
collection and organization, (B) analysis, and (C) interpretation of data.
(A) Collection and organization of data: We will see several methods of organizing
data: graphically (through the use of charts and graphs) and numerically (through the use of
tables of data). The type of organization we do depends on the type of analysis we wish to

This compendium aims at providing a comprehensive overview of the main topics that appear
in any well-structured course sequence in statistics for business and economics at the
undergraduate and MBA levels. The idea is to supplement either formal or informal statistic
textbooks such as, e.g., “Basic Statistical Ideas for Managers” by D.K. Hildebrand and R.L.
Ott and “The Practice of Business Statistics: Using Data for Decisions” by D.S. Moore,
G.P. McCabe, W.M. Duckworth and S.L. Sclove, with a summary of theory as well as with
a couple of extra examples.
(BQ) Part 2 book "The mathematics of money" has contents: Investments, retirement plans, mathematics of pricing, taxes, consumer mathematics, international business, financial statements, insurance and risk management, evaluating projected cash flows, business statistics.
