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