Seems like default graphic for oneway is dots. How do I change that to bars?
Many platforms include display options under the red-triangle menu:
Click on the triangle, and look to the bottom of the menu for the Display Options, which include box plots, mean error bars, and more:
I hope that helps!
A bar chart is a very poor representation for a oneway analysis of variance (ANOVA): it does not display variance!
The typical view is a boxplot or a probability plot which display both mean and variability. These plots display data anomalies such as outliers, modality (clusters) and stong skews in the data. In my opinion, and I believe most statisticians will agree, a bar chart is the least informative display for a Oneway analysis.
Use GraphBuilder if you want bar graphs of the means of groups.
