## Overview

Practice of Business Statistics : Using Data for Decisions / Edition 2

The Practice of Business Statistics offers a welcome innovation by allowing students to make data-informed, real-world business decisions almost from day one. By discussing data production and interpretation early in the book data analysis can then be used throughout the course. This approach drives home the relevance and usefulness of statistical ideas to the business world from the onset.

New Format Options
The Practice of Business Statistics responds to concerns about textbook length by offering instructors a number of alternatives:
A core book containing the first 14 chapters
Companion chapters on advanced inference topics (available on the book companion site, or through W.H. Freeman Custom Publishing):
15. Two-Way Analysis of Variance
16. Nonparametric Statistics
17. Logistic Regression
18. Bootstrapping Methods and Permutation Tests

Because real data are often messy and inference requires clean data, data analysis is an essential preliminary to inference. That is why data analysis is presented first, as Part 1.

Part I Data
Chapter 1 Examining Distributions

1.1 Displaying Distributions with Graphs
1.2 Describing Distributions with Numbers
1.3 The Normal Distributions
The first of two Chapters on data analysis: shows students how to look at data and summarize them graphically and numerically, introducing sampling distributions, repeated samplings, and standard deviation.

Chapter 2 Examining Relationships
2.1 Scatterplots
2.2 Correlation
2.3 Least-Squares Regression
2.4 Cautions about Correlation and Regression
2.5 Relations in Categorical Data
The second Chapter on data analysis: shows students how to analyze and summarize, graphically and numerically, data with two variables, introducing relationships between variables, correlation, and providing a preliminary introduction to least-squares regression.

Chapter 3 Producing Data
3.1 Designing Samples
3.2 Designing Experiments
3.3 Toward Statistical Inference
3.4 NEW Commentary: Data Ethics
Teaches students to look more deeply at where data sets come from and how to recognize good data from bad data.

Part II Probability and Inference
Chapter 4 Probability and Sampling Distributions

4.1 Randomness
4.2 Probability Models
4.3 Random Variables
4.4 The Sampling Distribution of a Sample Mean
The probability material that is needed to understand statistical inference.

Chapter 5 Probability Theory
5.1 General Probability Rules
5.2 The Binomial Distributions
5.3 The Poisson Distributions
5.4 Conditional Probability

Chapter 6 Introduction to Inference
6.1 Estimating with Confidence
6.2 Tests of Significance
6.3 Using Significance Tests
6.4 Power and Inference as a Decision
From Chapter 6 on, the book presents statistical inference, still encouraging students to analyze the data rather than quickly choosing a test from Excel.

Chapter 7 Inference for Distributions
7.1 Inference for the Mean of a Population
7.2 Comparing Two Means
7.3 Optional Topics in Comparing Distributions

Chapter 8 Inference for Proportions
8.1 Inference for a Single Proportion

10.2 Using the Regression Line
10.3 Some Details of Regression Inference

Chapter 11 Multiple Regression
11.1 Data Analysis for Multiple Regression
11.2 Inference for Multiple Regression
11.3 Multiple Regression Model Building

Chapter 12 Statistics for Quality: Control and Capability
12.1 Statistical Process Control
12.2 Using Control Charts
12.3 Process Capability Indexes
12.4 Control Charts for Sample Proportions

Chapter 13 Time Series Forecasting
13.1 Trends and Seasons
13.2 Time Series Models

Chapter 14 One-Way Analysis of Variance

15.2 Inference for Two-Way ANOVA

Chapter 16 Nonparametric Tests
16.1 The Wilcoxon Rank Sum Test
16.2 The Wilcoxon Signed Rank Test
16.3 The Kruskal-Wallis Test

Chapter 17 Logistic Regression
17.1 The Logistic Regression Model
17.2 Inference for Logistic Regression
17.3 Multiple Logistic Regression

Chapter 18 Bootstrap Methods and Permutation Tests
