Question

Quizplus · Accepted Answer

Creating a scatterplot is useful to visualize the relationship between two variables and determine if the relationship is linear, nonlinear, or has no relationship at all. It is not used to decide if the relationship is statistically significant or to prove research hypotheses. The decision to use a one-tailed or two-tailed alternative hypothesis is based on the research question and cannot be determined solely from a scatterplot.
