Analysis Overview

Crossover is a calculation based on the comparison of ranking of the samples using the means between the panel and the panelist.
A higher number indicates how much more outside of the panel they were for that attribute.
The crossover score can range from 0 to 100. The score is 0 if the panelist exactly matches the panel’s rank order of product means. The score is 100 if the panelist ranks the products exactly opposite to the panel’s ranking and all the products were significantly different from each other. If the Duncan’s grouping indicates at least two products were not significantly different, then a score of 100 is impossible.



  1. Mean . The mean of the crossover scores of all panelists by attribute.
  2. Panelists . The individual crossover score for the panelist by attribute.
  3. Highlighted cells . Indicate a score greater than the preset threshold.
For a visual representation of the intensities of the samples see the Product Mean Graphs sheet. For more information on the rank orders see Panelist Rank Orders and Rank Orders Graphs.

Example Conclusion

As we noted in the Product Mean Graphs and Panel Performance Summary, Noel has flipped the scales completely for the given attributes. This means the sample which was scored the highest by the panel was scored the lowest by Noel. Same for the other samples.

Tabitha was above the threshold for Sweetness Flavour, however she did not completely flip the scales for all products. Looking back at the Product Mean Graphs, we can conclude this is likely due to her scoring of Apple Juice 1, 2 and 3.
