Error Bars for Graphs in SPSS (4-5)

[@Truthfulpietro]

Hi my data keeps making this box show up: Warnings One or more error bar calculations yielded infinite results. These error bars have been removed from the chart. I don't know why it keeps doing this. Any advice?

Those kinds of errors pop up when you have limitations in your data. Check whether you are using an ordinal variable or something codes 1, 2, 3, &4 with such limited range that no error measure could be computed. Good luck!

can't determine two error bars are so close, is there anyway to determine if the lower error bar is same level of higher error bar in other factor?

[@ResearchByDesign]

The best strategy is to calculate the confidence interval around the mean and then see if it includes (a) the mean of the other sample/population mean, or (b) 0 for the mean difference. In either case, if the CI includes the mean or 0, the groups are NOT different. Cheers

If I want high or low error bar only, what should I do, thanks alot.

I don't know of a way to remove only one of the error bars. My workaround would be to export the graph and then erase a bar in Photoshop or similar program. Good luck

A graph is meaningless without errorbars and yet SPSS makes it nearly impossible to add them to anything that is not a bar graph. As if bar graphs are the only kind of graph that exists. What a horribly designed and poorly thought out program. All other programs do this seamlessly at the press of a button.

Thanks
