Statement B accurately describes what a scatter diagram is, while the other statements either contain inaccuracies or are too generalizing. Statement A is not always true, as the term "response variable" is typically used to refer to the dependent variable in regression. Statement C is also not always true, as the dependent variable can be plotted on either axis depending on the research question. Statement D is incorrect, as non-linear patterns can also exist in the relationship between variables. Therefore, statement B is the best choice.
