Question

Part I (approximately 1–1½ pages, total):
Copy and paste the following examples (1-6 below), then respond by classifying each of the
following variables as either: nominal, ordinal, interval, or ratio. Provide a
ief
explanation where indicated.
1. A researcher studying lifespan categorizes individuals into single, ma
ied, divorced, or
widowed. What type of variable measurement is this?
Answer – This is a type of Nominal variable. This is because the categories are mutually
exclusive and does not have an order of any value above or below, more or less than the
other.
2. A cognitive scientist places her subjects into categories based on how anxious they tell her
that they are feeling: “not anxious,” “mildly anxious,” “moderately anxious,” and
“severely anxious,” and she uses the numbers 0, 1, 2 and 3 to label categories where lower
numbers indicate less anxiety. What type of variable measurement is this? Are the
categories mutually exclusive?
Answer – This categorization is an example of Ordinal Variable because as the label
categories go high starting from 0 to 1 to 2 to 3, the anxiousness is increasing from Not
Anxious to severely anxious by the end. However, the measurement of increase in
anxiousness from 0 to 1 may not be similar from that of 1 to 2.
Secondly, yes, the categories are very much mutually exclusive due to the fact that no subject
can be “not anxious” and “moderately anxious” at the same time. Likewise comparison
can be drawn between any variables to understand that no category overlaps each other.
3. A Physician diagnoses the presence or absence of disease (i.e., yes or no). What type of
variable measurement is this?
Answer – This is a type of Nominal variable of further “dichotomous” category. The
categories here are also mutually exclusive, do not have an order of any value and
additionally have only 2 categories.
4. A person weighing 200 lbs. is considered to be twice as heavy as a person weighing 100
lbs. In this case, what type of measurement is body weight?
Answer – Weight belongs to Ratio...
