Analyse data from open card sorting

---

A Python package to cluster and visualize data from open card sorting tasks

Cardsort helps UX researchers quickly analyse data from open card sorting exercises using hierarchical cluster analysis. This task helps to understand how people organize information, and is frequently used to develop information architectures for websites. Click here to learn more about the card sorting method.

More precisely, cardsort helps you to:

• Create distance matrices using hierarchical cluster analysis
• Create dendrograms from based on these matrices
• Extract user-generated category-labels
• Using data exports from kardsort.com

Quick start

Installation

$ pip install cardsort

Usage

cardsort can be used to create dendrograms and extract user-generated category-labels:

from cardsort import analysis
import pandas as pd

path = "example-data.csv" # data with columns: card_id, card_label, category_id, category_label, user_id
df = pd.read_csv(path) 

The data used in this example can be found under /docs/example-data.csv.

Create a dendrogram that summarizes user-generated clusters

analysis.create_dendrogram(df)

Output

Learn which category labels users gave to clusters

cards = ['Banana', 'Apple']
analysis.get_cluster_labels(df, cards)

Output

  user_id   cluster_label                                              cards
0       2  Healthy snacks                                    [Banana, Apple]
1       3          Snacks     [Sandwich, Croissant, Banana, Mooncake, Apple]
2       4          Fruits                                    [Apple, Banana]
3       5            Food  [Banana, Croissant, Apple, Sandwich, Hot Dog, ...

Interpretation: In this case, the users with IDs 2 and 4 made clusters containing exactly the two cards of interest ('Banana' and 'Apple', as specified in the input variable 'cards'). User 2 labelled this cluster 'Healthy snacks', and user 4 'Fruits'. Users 3 and 5 also clustered these cards together, but they included additional other cards in the same cluster, and labelled the cluster 'Snacks' or 'Food'. User 1 does not appear in the output, because they did not cluster the cards together.

Accepted data

• This package works with data exports from kardsort.com (Export format 'Casolysis Data (.csv) - Recommended') or other data following the same structure.
• Columns: card_id, card_label, category_id, category_label, user_id
