Using inferential intervals to compare groups When comparing two sets of results, e.g., from n knock-out mice and n wild-type mice, you can compare the SE bars or the 95% CIs What Do Error Bars Show Method 3 - Using Plot Details Dialog for 3D Graphs Error bars also could be added in the 3D graph from existing datasets by the Plot Details dialog.

E.g 12,12,11,10,10 my average is 11 but would putting the error bar from between 12 and 10 be a range bar not an error bar??

Means and SE bars are shown for an experiment where the number of cells in three independent clonal experimental cell cultures (E) and three independent clonal control cell cultures (C) was
