Statistics cards in a worksheet provide a straightforward way to perform various statistical tasks for a dataset without cluttering the Flow.

In Dataiku, a card is used to perform a specific EDA task. For example, you can describe your dataset, draw inferences about an underlying population, analyze the effect of dimensionality reduction, and so on.

Creating cards#

When creating a card, you can specify the card type and its corresponding parameter values. If you’re not sure which card to choose or you just want to explore, you can select Automatically suggest analyses to start examining your data.

Once created, cards appear below the worksheet header. To streamline your worksheet view, you can expand or collapse any cards to show or hide their contents.

Configuration menu#

All cards have a configuration menu that lets you:

  • Edit card settings.

  • Configure tests.

  • Duplicate or delete the card.

  • View the JSON payloads and responses to leverage the public API.

  • Publish the card to a dashboard.

  • Export the card as a recipe (Select card types only).

Some cards also contain multiple sections, with each section implementing separate statistical tasks. In these cards, the sections and tasks can have their own configuration menus for changing settings at a more granular level.

Split by#

Finally, the Split by option in a card is useful for grouping your dataset by a specified variable. This allows the card to perform computations on each data subgroup.
