.. _auto_dataset_compute_averages:

*DATASET COMPUTE AVERAGES*
==========================

Computes the column-wise mean for one or more columns in a dataset and returns the results as a new single-row dataset. Use this worker to quickly summarize numeric columns without writing custom expressions.

When to use
-----------

Classification: **process**.

Tagged: ``aggregation``, ``column_stats``, ``compute_averages``, ``dataset_transform``, ``mean``.

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

     - Default
     - Required
     - Description
   * - Dataset
     - dataset_1
     - dataset
     - —
     - 
     - Input dataset whose columns will be averaged; accepts any tabular dataset — leave unconnected only if the worker is being tested in isolation.
   * - Columns
     - columns
     - scalar
     - —
     - 
     - One or more column names to average; supports multi-select driven by the connected dataset. Leave blank (default) to compute averages for all numeric columns.
