- TL;DR Summary
- Choosing which variable is the dependent or independent variable

Hello,

I am review some basics. In the case of two variables like ##t## and ##C##, which represent the time in year and the cost in $ of a product respectively, we can graphically represent this pair of variables on a Cartesian plane. The horizonal axis is generally assigned the variable ##t## and the vertical axis to the variable ##C##.

The horizontal axis is commonly reserved for the independent variable and the vertical one for the dependent variable. But this idea of dependent/independent or cause/effect does not always apply. For example, there many not be any cause/effect or "dependence" between the two variables. We are just pairing them and visualize the pairs of values as points.

So, in general, given two variables, how do we choose which one to assign to the horizontal axis and which to the vertical axis? What is the best practice criterion? We can clearly do things the other way without breaking any rule. Is the vertical axis for the variable that we consider...

For example, if ##n## is the number of clicks and ##p## is the number of purchases associated to the number of clicks, we can form the ordered pairs ##(n,p)## or also the ordered pairs ##(p,n)## and plot these pairs as points either in the graph "p vs n" or "n vs p"...

Thanks
