Document Summary
Scatter plot graph - a graph that depicts the relation between two scale variables. No relation: looks like a jumble of random dots. Linear relation: the relation between variables is best described by a straight line. Nonlinear relation: the relation between variables is best described by a line that breaks or curves in some way. Line graph - a graph that is used to illustrate the relation between two scale variables. Time plot: a graph that plots a scale variable on the y-axis as it changes over an increment of time labeled on the x-axis. Bar graph - a visual depiction of data in which the independent variable is nominal or ordinal and the dependent variable is scale. Independent variable (x - axis): nominal or ordinal. Describe the data as (what you are measuring) on the (test name) test . The height of each bar typically represents the average value of the dependent variable for each category.
