Question

Quizplus · Accepted Answer

The x-axis, also known as the abscissa, is the horizontal line on which the different values appear in the graph of an interval level variable. The point of origin is where the axes intersect, and the y-axis, or ordinate, is the vertical line on which the variable is plotted. Percentile rank is a measure of the value's relative standing within a distribution and is not directly related to the axis in a graph.
