Statistics in Business According to Lind (2011), statistics is defined as “the science of collecting, organizing, presenting, analyzing, and interpreting data to assist in making more effective decisions.”

Types of Statistics

There are two different types of statistics. The first type is known as descriptive statistics. According to McClave (2011), descriptive statistics “utilizes numerical and graphical methods to look for patterns in a data set, to summarize the information revealed in a data set, and to present the information in a convenient form.” The second type of statistics is the inferential statistics. This type of statistics “utilizes sample data to make estimates, decisions, predictions, or other generalizations about a larger set of data (McClave, 2011).”

Levels of Statistics

Statistics have four different levels. These levels are often referred to as levels of measurement. This first level is known as a nominal level. Within this level, data is sorted into categories without an order. The second level is the ordinal level. This is where the level of measurement decides if any one category is to be ranked higher than another. The third level is known as the interval level. Within this level, “the ranking characteristics of the ordinal level of measurement plus the characteristic that the distance between values is a constant size (Lind, 2011).” The last level is the ratio level. This level has “all of the characteristics of the interval level, plus there is a zero point and the ratio of two values are meaningful (Lind, 2011).”

Statistics play an important role in business because it allows businesses to measure performance and forecast future targets. Businesses use statistics to study facts and...

...Organizational structure refers to the way that an organization arranges people and jobs so that its work can be performed and its goals can be met. When a work group is very small, and face-to-face communication is frequent, formal structure may be unnecessary, but in a larger organization decisions have to be made about the delegation of various tasks. Thus, procedures are established that assign responsibilities for various functions. It is these decisions that determine the organizational structure. In an organization of any size or complexity, employees' responsibilities typically are defined by what they do, who they report to, and for managers, who reports to them. Over time these definitions are assigned to positions in the organization rather than to specific individuals. The relationships among these positions are illustrated graphically in an organizational chart. The best organizational structure for any organization depends on many factors including the work it does; its size in terms of employees, revenue, and the geographic dispersion of its facilities; and the range of its businesses (the degree to which it is diversified across markets). DEVELOPMENT OF THE TRADITIONAL ORGANIZATIONAL STRUCTURE Understanding the historical context from which some of today's dominant organizational structures have developed helps to explain why some structures are the way they are. For instance, why are the old, but still operational steel mills such as U.S. Steel and......

...CERTIFIED PUBLIC ACCOUNTANTS AND CONSULTANTS TO BUSINESS Working Capital Management Strategies Working capital strategies has in the past been a responsibility designated to those managers in the accounting and finance departments. However, today’s economy is changing those roles and many managers who traditionally were not part of this process are being called upon to take proactive steps in reducing the risk associated with working capital. Working capital may be a foreign term to some managers and so we should first begin by defining this term. Generally working capital represents those current assets such as cash, marketable securities, accounts receivable, inventory and pre-paid expenses. Furthermore net working capital would take the calculation further and reduce working capital by the current liabilities such as accounts payable, short term borrowings and accrued liabilities. Understanding these terms is crucial because a company’s daily activities typically result in dramatic fluctuations in the accounts comprising working capital. The manager’s ability to anticipate the fluctuation and proactively make decisions to curtail the negative impact of such fluctuations will help maintain liquidity even in the toughest of circumstances. A company’s ultimate long-term success is based upon all departments within the organization coming together to fulfill its business purpose or mission. The same ideology should be used in managing the company’s working......
