Discussion 1 – Types of Data

Give an example of a research question
that includes an independent and a dependent variable.  These are usually
presented as, “How does A affect B?”, where A is your independent
variable and B is your dependent variable.  Describe the independent and
dependent variables in terms of whether they are nominal (also called
categorical), ordinal, interval, or ratio variables (interval or ratio variables
are also called continuous variables).  How would you study this research
question?
