What is the argument for choosing to create a line graph instead of a bar graph to illustrate some effects of repeated-measures designs? Repeated-measures descriptive statistics are always presented using line graphs and between- subjects descriptive statistics are always presented using bar graphs. When the repeated-measures variable includes measurements over time, a line implies continuity. Actually, repeated-measures descriptive statistics are always presented in tables. You cannot add standard deviations to a line graph and you never report standard deviations with repeated-measures data
