Data Collection Systems
Paper details:
Read through Chapter 1, then review the pictures contained in the examples of Data Collection SystemsPreview
the documentView in a new window 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 variableÕÉ≠†Њ†s. 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
