Question

If "f" is an explanatory variable and "g" is the corresponding response variable, which of these would be represented by the horizontal axis on a scatterplot?

a. "f"
b. "g"
c. neither f or g
d. both f and g

Answer 1

well, since g depends on f, we have a function g(f) in a usual looking graph, y depends on x so y and g should share a common axis

Answer 2

The variable that is represented on horizontal axis is:

f

Explanation:

If "f" is an explanatory variable and "g" is the corresponding response variable, this means that 'f' is the independent variable and 'g' is the dependent variable since it depends on the value of 'f'.

Also in the scatter plot the horizontal axis denotes the input values or the independent variable and g represents the output value or the dependent variable.

Hence, f would be represented by the horizontal axis on a scatter plot.
