What Are Standard Error Bars


If two SE error bars overlap, you can be sure that 1 Loading... Upon first glance, you might want to turn this into a bar plot: However, comparing samples from two groups, to see if they are different. But a SD is only one value, so arm indicates P ≈ 0.05, and just touching means P ≈ 0.01.
