Create an interval plot of one Y variable with groups

Graph > Interval Plot > One Y > With Groups or Stat > ANOVA > Interval Plot > One Y > With Groups

Complete the following steps to specify the data for your graph.

  1. In Graph variables, enter one or more columns of numeric or date/time data that you want to graph. By default, Minitab creates a separate graph for each variable.
  2. In Categorical variables for grouping (1-4, outermost first), enter up to four columns of categorical data that define the groups. The first variable is the outermost on the scale and the last variable is the innermost.

In this worksheet, Height is the graph variable and Fertilizer is the categorical variable for grouping. The graph shows the confidence interval for the mean for each fertilizer type.
