, Teaching Tips 5
Chapter 1
You need to continue the discussion of the Define task by establishing the types of variables. Mention the
TU
importance of having an operational definition for each variable. Be sure to discuss the different types
carefully because the ability to distinguish between categorical and numerical data will be crucial later in
the course. Go over examples of each type of variable and have students provide examples of each type.
Then, if you wish, you can cover the different measurement scales.
V
Then move on to the C of the DCOVA approach, collecting data. Mention the different sources of
data and make sure to cover the fact that data often needs to be cleaned of errors. Then, you could spend
IA
some time discussing sampling, even if it is just using the table of random numbers to select a random
sample. You may want to take a bit more time and discuss the types of survey sampling methods and
issues involved with survey sampling results. The Think About This essay discusses the important issue of
?_
the use of Web-based surveys.
There is also a section on Data Cleaning that discusses the issues that occur in data collection.
This is followed by a section on data formatting that includes the important concepts of stacking and
AP
unstacking variables and recoding variables. The last section discusses the types of errors that occur in
surveys.
The chapter also introduces three continuing cases related to the Managing Ashland MultiComm
Services, CardioGood Fitness, and Clear Mountain State Student Surveys that appear at the end of many
PR
chapters. The Digital Cases are introduced in this chapter also. In these cases, students visit Web sites
related to companies and issues raised in the Using Statistics scenarios that start each chapter. The goal of
the Digital Cases is for students to develop skills needed to identify misuses of statistical information. As
would be the situation with many real-world cases, in Digital Cases, students often need to sift through
OV
claims and assorted information in order to discover the data most relevant to a case task. They will then
have to examine whether the conclusions and claims are supported by the data. (Instructional tips for
using the Managing Ashland MultiComm Services, and Digital Cases and solutions to the Managing
Ashland MultiComm Service, CardioGood Fitness, Clear Mountain State Student Surveys, and Digital
ED
Cases are included in this Instructor’s Solutions Manual.).
Make sure that students read the Excel Guide and/or JMP Guide or Minitab Guide at the end of
each chapter. The Workbook Excel instructions provide step-by-step instructions and live worksheets that
automatically update when data changes. The PHStat Excel instructions provide instructions for using the
??
PHStat add-in with Excel. The Analysis ToolPak instructions provide instructions for using the Analysis
ToolPak, the Excel statistical add-in that is included with Microsoft Excel.
