Citrin Mean/Median Bar and Line Charts

A two-way mean or median bar plot allows comparing mean or median values of response data (scores, measurements) obtained from pq levels of two experimental factors (i.e., k=pq samples/groups).

Required Worksheet Layout

Here, a categorical column stores levels of a grouping variable (i.e., the 1^st factor), and two or more numeric columns store response values (scores, measurements), each corresponding to only one level of the 2^nd factor but all levels of the 1^st factor.

• The chart legend entries represent the response variables; the X-axis labels represent levels of the grouping variable.

The one-way plots are designed for comparing mean/median values of response data from k>=2 samples/groups, with response values of each group being stored in a separate numeric column, i.e., no grouping variable is required to split the data into its subsets.
