How do I interpret the Similarity Matrix in Card Sorting?

This section covers how to use the Similarity Matrix in open and hybrid card sort analysis to:

• Find commonly grouped card pairs

Find commonly grouped card pairs 

• The similarity matrix provides an easily readable representation of the frequency of pairings being grouped together.
• The higher the percentage and darker the shade of blue where two cards intersect, the more often they were grouped together.
• Click a pairing in the matrix to display a list of categories that contained said pairing and the list of respondents who submitted them.

Similarity matrix

The matrix shows which cards were coupled together most often and clusters similar cards along the diagonal edge.

Inspect card couples

Clicking a pair of cards reveals the names of categories that the pairs shared together, as well as the respondents who put them there.
