How to obtain both std dev and std error mean in each y error bar
I am making column charts in Excel. Does anyone know if it is possible
in Excel to setup the y error bar for each series so that it provides multiple values? I would like dash marks, one for the std deviation and one for std error mean, on the same vertical line. I've seen it done elsewhere, and would be suprised if Excel doesn't have this feature, but can't seem to find it. Also, when I calculate the std error mean or the std deviation in Excel, the returned value equals the size of the error in one direction (ex. positive or negative) right? So if I use this value for a y error bar, I should put it in twice, once in the positive box and once in the negative box, which graphically doubles the total size of my error. Is this correct, or is the value itself already accounting for error in both directions, so that I should halve the value before putting it in each box? Thanks for your help, Kerry |

How to obtain both std dev and std error mean in each y error bar
You could plot two identical series and use the standard deviation for one
error bar and standard error mean for the other error bar. Just change the points for one of them so that they aren't displayed. "Augabog" wrote in message oups.com...

What do you mean by "change the points for one of them so that they
aren't displayed."? I plotted two identical series in the same graph, and then added a different error bar on each.This creates two equally sized column adjacent to each other. What points do I change to make the two y error bars be displayed on only one of these identical columns? If it is possible, it would be best if they completely overlap. Thanks again, Kerry |
