A recent study considered the number of degrees awarded in certain regions of the world.
Region: United States Western Europe Asia
Engineering 61,941 158,931 280,772
Natural Science 111,158 140,126 242,879
Social Science 182,166 116,353 236,018
(a) How many variables do we have? What kind of variables are they?

a) Four variables( Region, number of degrees awarded in engineering, number of degrees awarded in natural sciences, number of degrees awarded in social sciences)

Region is categorical variable while Number of degrees awarded in engineering, Number of degrees awarded in natural sciences, Number of degrees awarded in social sciences are Quantitative discrete variables.

Step-by-step explanation:

a) There are four variables regions, number of degrees awarded in Engineering, number of degrees awarded in Natural sciences, number of degrees awarded in Social sciences.

Region is a categorical variable whereas number of degrees awarded in engineering, natural sciences and social sciences are quantitative discrete variable.

Region is a categorical variable because can be divided into categories United states, Western Europe and Asia.

The number of degrees awarded in Engineering, number of degrees awarded in Natural sciences and number of degrees awarded in Social sciences are quantitative variables because they can be numerically interpreted in a meaningful way. Also they are discrete quantitative variable because number of degrees awarded are countable.
