Analysis of Card Sorting Results

In this guide, we are going to show you how you can analyze the results of your Card Sorting study conducted with UXtweak.

UXtweak analyzes the results of your card sorting study by calculating metrics and aggregations that make the outcome of your study easier to interpret than if you were looking at responses one by one.

This allows you to look at the data from various perspectives. The analytics include a number of grids and diagrams that reflect the connection of cards to each other as well as to categories. 

While some analytics are exactly the same in every Card Sorting, others differ depending on whether your Card Sorting is open, closed or hybrid.

Open and hybrid studies are oriented towards exploration of card relations and the meaning of categories. Closed card sorting results focus more on the evaluation of the pre-defined category model. Let’s take a look at Card Sorting results and what you can do with them.


The Overview section is a mainstay of every UXtweak study results. It shows you a quick summary of how your study is going. Here you can find the median time taken to complete your card sorting, which tells you if your study has an appropriate length. In the top locations, you can keep track of the countries that your respondents come from.

Handy donut charts give you the information on how many respondents have participated in the study and how many of them managed to actually complete it.

The Respondents section provides you with detailed profiles of your respondents. Here you can see when they started the study, how long it took them, what device they used, their location and browser information. The respondent details will also show you how the respondent answered the questions and how they sorted cards into categories. 

With each respondent, you can choose if you want to include them in the analysis or not, to analyze them in segments or to filter out the ones that you think are irrelevant. With filters, you choose to only display the ones who meet a certain criteria (age, time it took them to complete the study, etc.)

The answer to the Screening question, as well as the results of Pre-Study and Post-Study questionnaires are all found in the Questionnaire Analysis. Beneath the question’s text, you can find all the answers along with the number of users who submitted them.

Cards and Categories

Simply put, the Cards analysis and the Categories analysis are two sides of the same coin. For every card, the Cards analysis sums up which categories it was placed into. Meanwhile, the Categories analysis shows you all the categories (predefined or respondent-defined) and it tells you which cards are in it. In open and hybrid Card Sorting, here you can also standardize your categories. Standardization is when you decide that two or more categories created by different respondents are actually the same category.

Standardization Grid and Results Matrix

Standardization Grid shows you the distributions of cards between standardized categories. It is generated from the results of an open and hybrid Card Sorting. The blue color of the cells visually represents the percentage of users who sorted that card into the original categories that the standardized category was made from. The darker the shade, the higher the number. It’s an easy way to get an overview of how the cards were placed.. 

The Results Matrix is a very similar analysis specific to closed Card Sorting. Since there’s no need for standardization, here it shows you how many times each card was sorted into any of the predefined categories.

Popular Placements Matrix

This analysis can give you quick answers when you’re conducting a closed Card Sorting study. Particularly if your question is: “Where would the majority of people place each of these cards?”. With dark hue, it shows you the popular placements – the most popular category for each individual card.

Similarity Matrix

The Similarity Matrix puts all the cards in a grid which shows how often each individual pair of cards was placed into the same category. This is ideal for finding clusters of cards that belong with each other, regardless of what exact categories they were sorted in.. The percentage of each grouping is also visually represented by different shades of the blue color. The darker the shade, the more is the percentage. By clicking the numbers you can see the names of categories in which the respondents commonly group these cards.

Analysis of Card Sorting Results


Dendrograms are related to the Similarity Matrix in that they show relationships between cards but in a different manner. Instead of a grid, you get a tree-like diagram, where the branches represent cards that were grouped together by a certain number of respondents. The higher the branches, the higher the percentage of people who agree that these cards belong together.

Respondent-Centric Analysis 

The Respondent-Centric Analysis (RCA) takes a different view at card sorting results. It automatically finds respondents who are the best representatives of popular sorting strategies that were utilized by your respondents. If there are segments of your audience characterized by different ways of thinking, the RCA will find them and show you what their approaches are.
