Task 1: NOMINAL DATA – Data Collection and Operational Definitions
Nominal data is also known as qualitative because the data items differ on the basis of qualities
that can be described by words but not numbers. The researcher uses ‘operational definitions’ to
ensure the items are categorized accurately. ‘Operational’ acknowledges that the definition
applies specifically to your activities (operations,) and that other definitions may exist. After
categorization, the items can be counted and ‘frequencies’ are obtained. Note that frequencies
are part of data organization; they are not nominal data. Definitions also show others how the
research was conducted. Similar principles apply in areas such as Law. Professional literature in
many fields begins with a Definitions section.
Use your own items for this task. Choose a variable from the options below. You should have a
total of at least 25 items which can be sorted into exactly 4 categories.
Choose ONE of the following to be your Nominal Variable:
Clothing Art/Craft materials Books

The Variable Name is descriptive of all the items. You may use the name given in the list or
choose a more specific name if it seems appropriate. Provide a clear and concise definition.
Categories within a nominal variable are based on the qualities that only some items share. Give
a clear, concise operational definition of each category (40 word maximum.) The definition
should be clear enough that anyone else would be able to sort the entire collection exactly the
way you did. Examples of items in each category may be included after the definition.
A completed example of the assignment, and notes to help with the quizzes are posted in the
Discussions area of the course, along with other resources.
Provide operational definitions for your nominal variable and its categories. The table and graph
must follow the same order, so give some thought to the order used. Since this is a nominal
variable, you can follow any system that makes sense to you.
