Existing data source B. Observational data source C. Experimental data source D. Cross-sectional data source One method of determining whether a sample being studied can be used to make statistical inferences about the population is to: Run a descriptive statistical analysis B.

Calculate a proportion C. Create a cross-sectional data analysis D. Which of the following is NOT an example of unethical statistical practices? Inappropriate interpretation of statistical results B. Using graphs to make statistical inferences C. Improper sampling D.

Descriptive measures that mislead the user E. None of these Cross-sectional B. Time series A study is being conducted on the effect of gas price on the number of miles driven in a given month. Residents in two cities, one on the East Coast and one on the West Coast are randomly selected and asked to complete a questionnaire on the type of car they drive, the number of miles they live from work, the number of children under 18 in their household, their monthly income, and the number of miles they have driven over the past 30 days.

List the response variable s. Is this an experimental or observational study? List the factor s. Looking at the runs plot of gasoline prices over the past 30 months, describe what it tells us about the price of gas during these 30 months.

Using the following data table of the average hours per week spent on Internet activities by to year-olds for the years , construct the runs plot and interpret. Reflective Thinking Blooms: Remember Difficulty: Population 2. Understand Difficulty: Population 3. Random Sampling 4. Variable 5. Variable 6. Time Series Data 8. Cross-Sectional Data 9. This is an example of time series data. Time series data are collected at different time periods.

Time Series Data The cumulative GPA is an example of a variable, which is a characteristic of the element college business students. Data Data Sources FALSE In experimental studies, the aim is to manipulate the factor, which is related to the response variable.

Statistical inference is the science of using a sample of measurements to make generalizations about the population of measurements. Statistical Inference Random Sampling FALSE Using different samples and tests to produce a desired conclusion does not make the conclusion true. Ethics Blooms: Ethical Guidelines Predictable By definition, ratio variables are quantitative and have an absolute zero value.

Whether a person has a charge account A quantitative variable is measurable and noncategorical. Value of company stock A categorical variable is qualitative, not measured. By definition, elements and variables are the same; processes are not measurements. Nominative and interval Nominative and ordinal are types of qualitative variables.

Ratio Temperature is quantitative excludes nominative and ordinal and the ratio of two temperatures is not meaningful. Ratio Interval and ratio are quantitative variables; jersey numbers have no logical order. Ratio Nominative and ordinal are qualitative variables; weight creates logical ratios: Ratio Interval and ratio are quantitative variables, nominative is only a naming category, and police rank has order. Cross-sectional data A runs plot is a graphical display of time series data.

Statistical inference By definition, a time series is a study of data over time; descriptive statistics is the study of the measurements of population variables; a random sample is a data set. Interval Nominative and ordinal are qualitative variables; exam scores have no meaningful ratio and no inherently defined zero value. Ratio Nominative and ordinal are qualitative variables; miles driven can have a meaningful ratio.

Interval Ratio and interval are quantitative variables; ordinal implies order or rank. Ratio This is a qualitative variable without order; therefore, a nominative variable. Variable Measurement and observation are methods attached to a variable; a sample is a subset of the units in a population. Variable By definition, a census looks at the entire population. Census A process is a sequence of operations; a census looks at the entire population; set is related to population.

Observational analysis By definition, sampling is taking a portion of the population to measure; experimental and observational analysis are methods of obtaining data. Measurement A runs plot is a graphical display of data over time. Inference By definition, inference is taking a sample of data and its measurements and relating those measurements to the population as a whole.

Sample Variable By definition, a census looks at an entire population; a variable is a characteristic of an element within the population; a process is a sequence of operations that produces elements of a population.

Nominative Qualitative, categorical, and nominative have similar definitions. Random sampling By definition, a runs plot is a graphical display; random sampling is a method of selecting a portion of a population; statistical inference is the science of using a sample of measurements to infer about the entire population.

Interval Quantitative, ratio, and interval all have similar definitions. Population By definition, a census is the examination of all population measurements; a process is a sequence of operations; a sample is a subset of a population.

Time series analysis A runs plot and time series analysis both look at data over time; cross-sectional analysis looks at data collected at the same point in time. Descriptive Statistics Quantitative Qualitative and ordinal have similar definitions; random variables are all characteristics of a population element.

Measurements Existing data source B.

Descriptive Statistics Together with Bruce L. Bowerman, he has written 19 textbooks. Koehler ; and Linear Statistical Models: Professor O'Connell has published a number of articles in the area of innovative statistical education. He is one of the first college instructors in the United States to integrate statistical process control and process improvement methodology into his basic business statistics course.

He with Professor Bowerman has written several articles advocating this approach. Professor O'Connell received an M. In his spare time, Professor O'Connell enjoys fishing, collecting 's and 's rock music, and following the Green Bay Packers and Purdue University sports. Emily S. Murphree Emily S.

She received her Ph. In , she was named one of Oxford's Citizens of the Year for her work with Habitat for Humanity and for organizing annual Sonia Kovalevsky Mathematical Sciences Days for area high school girls. Every topic has a new example. Most concepts and formulas, particularly those that introductory students find most challenging, are first approached by working through the ideas in accessible examples. Once students have a clear understanding from these examples, more general concepts and formulas are then discussed.

Completely rewritten and simplified the introduction to confidence intervals in Chapter 8: New Chapter Statistical Inferences for Population Variances: Experimental Design and Analysis of Variance: Optional 7-page introduction to Box-Jenkins methodology: Reduced page count: Retained Features Business Improvement Conclusions that explicitly show how statistical results lead to practical business decisions: After appropriate analysis and interpretation, examples and case studies often result in a business improvement conclusion.

To emphasize this theme of business improvement, new icons have been placed in the page margins to identify when statistical analysis has led to an important business conclusion. Each conclusion has been highlighted in yellow for additional attention.

A shorter and more intuitive introduction to business statistics in Chapter 1: Chapter 1 begins with an improved example introducing what data are and how they can be used to make a successful offer on a house.
