F-Chart

Definition of F-Chart:

A chart that carries a significant amount of misleading information, rendering it unfit for the intended analysis. A good example of an F-Chart can be found in the boxplots output of the 2-Sample t-test, and One Way ANOVA in Minitab (14). The presence of a line connecting the means of each subgroup serves no apparant purpose, and could potentially mislead the reader into thinking that a steep gradient indicates a significant difference. The “F” comes from the latin ‘fuccant.’
