Question

Students will examine and interpret 14 variables from a random sample of 1450 birth records taken by the North Carolina State Center for Health and Environmental Statistics in 2001, and communicate the information by describing the data set, both graphically and numerically, in the form of a PowerPoint presentation.

Question: Classify each variable in the study as qualitative or quantitative. Explain why you classified the variable in that way?

Question: Use the data in the study to provide an example for each level of measurement (nominal, ordinal, interval, ratio). If any of the levels is missing, propose a new variable to illustrate it.
