C) a continuous variable
D) an independent variable

The ordinate of a graph labeled as "density" is typically used for continuous variables, as it represents the distribution of the variable over a range of values. Density refers to the amount of the variable that exists within a particular interval or range of values, so it makes sense to use this label for continuous variables, which can take on any value within a certain range. Discrete variables are characterized by individual, separate values (like the number of children in a family), and positively skewed variables are those with a distribution that is weighted towards higher values. Independent variables, on the other hand, are typically plotted on the horizontal (x) axis of a graph, whereas density is a label used for the vertical (y) axis.
