Answer:
Qualitative or categorical variable
Step-by-step explanation:
The month will be qualitative or categorical variables because it divides into 12 different categories such as January, February, March, April, May, June, July, August, September, October, November and December.
We want to see which type of variable does month represents in the revenue as a function of time. We will see that months are the independent variable.
In functions like:
y = f(x)
We have two types of variables, the independent variable, x, which can change freely, and the dependent variable, y, which changes in response to the value of the independent variable.
Here we have:
r = f(m)
r = revenue
m = month
So the revenue is a function that depends on the months, thus, m is the independent variable.
