Data, Data, and More Data
The preface to the text starts with the
statement, “This is a book about data” (p. xiii). The title of Chapter One is,
“Introduction to Data” and the first sentence in the chapter says, “Statistics
is the science of data...” (p. 3). Based on that, it seems that a good place to
start would be with a discussion about data. What is (or are) data? Section 1.1
in the text answers that question. Section 1.2 then discusses two types of
variables, categorical and numerical. Determining whether a variable is
categorical or numerical is important because the type of variable is important because
the type of variable determines the appropriate statistical techniques to use
in studying the variable.
Read
Read through Chapter 1, then review
the pictures contained in the examples of Data Collection
Systems found
in the PDF file. Notice that all of them show ways that you may use data or
summaries of data every day— or perhaps ways that your personal data are
collected and used by others. They also include both categorical and numerical
variables. For example, in the parking garage sign shown in the file, the
variable is the number of parking spaces available on each floor of the garage.
That would be a numerical variable. One of the pieces of information given on
Spokeo.com is the occupation of the person. That would be a categorical
variable.
Post
Post three paragraphs to this week’s discussion:
·
Explain how you use data –
or summaries of data – every day. Consider how you provide data for others to
use.
·
Give two specific examples
from your daily data, one numerical variable and one categorical variable.
Describe the data that would be collected on each (such as the units of
measure, integers or decimals, whether there’s a fixed number of categories or
free response).
·
Reflect on how the use of
your example data impacts your life/work or that of others.
