We focus on business applications, but we also use many exercises and examples that relate to the current world of the col- lege student. A previous course in statistics is not necessary, and the mathematical requirement is first-year algebra. In this text, we show beginning students every step needed to be suc- cessful in a basic statistics course.
This step-by-step approach enhances performance, accelerates preparedness, and significantly improves moti- vation.
Understanding the concepts, seeing and doing plenty of examples and exercises, and comprehending the application of statistical methods in business and economics are the focus of this book.
The first edition of this text was published in At that time, locat- ing relevant business data was difficult. That has changed!
Today, locat- ing data is not a problem. The number of items you purchase at the gro- cery store is automatically recorded at the checkout counter.
Phone companies track the time of our calls, the length of calls, and the iden- tity of the person called. Credit card companies maintain information on the number, time and date, and amount of our purchases. Medical devices automatically monitor our heart rate, blood pressure, and tem- perature from remote locations.
A large amount of business information is recorded and reported almost instantly. Today, skills are needed to deal with a large volume of numerical information. First, we need to be critical consumers of information pre- sented by others. Second, we need to be able to reduce large amounts of information into a concise and meaningful form to enable us to make effective interpretations, judgments, and decisions.
All students have cal- culators and most have either personal computers or access to personal computers in a campus lab. Statistical software, such as Microsoft Excel and Minitab, is available on these computers.
The commands necessary to achieve the software results are available in a special section at the end of each chapter. We use screen captures within the chapters, so the student becomes familiar with the nature of the software output. Because of the availability of computers and software, it is no Ionger necessary to dwelI on calculations.
Solutions by Chapter
We have replaced many of the calcu- lation examples with interpretative ones, to assist the student in under- standing and interpreting the statistical results. In addition, we now place more emphasis on the conceptual nature of the statistical topics. While making these changes, we still continue to present, as best we can, the key concepts, along with supporting interesting and relevant examples.
We have made changes to this edition that we think you and your stu- dents will find useful and timely. The new example includes more variables and more observations. It presents a realistic business situation.
It is also used later in the text in Chap- ter We have also increased the size and clarity of these screenshots. We have added many new or revised exercises throughout.
You can still find and assign your favorites that have worked well, or you can introduce fresh examples. The baseball data has been updated to the most current completed season, A new business application has been added that refers to the use and maintenance of the school bus fleet of the Buena School District.
Each chapter begins with a set of learning objectives designed LO1 Explain the concept of central tendency. LO2 Identify and compute the arithmetic mean. These objectives, located in the margins next to the topic, LO3 Compute and interpret the weighted mean. LO5 Identify the mode. LO6 Calculate the geometric mean. LO8 Compute and explain the variance and the standard deviation.

The variance is non-negative and is zero only if all observations are the same. Definitions Variance and standard deviation are based on Population Variance The formulas for the population variance and the sample variance are slightly different.
The population variance is considered first. Recall squared deviations from that a population is the totality of all observations being studied. The population Definitions of new terms or terms unique to the the mean. In addition, a formula card is bound into the back of the text, which lists all the key formulas.
