![]() Any count with “Non Null” in the name will only skip any records that do not have a definite value in the target field. The count options all provide record-counting aggregations. The next set of entries (up to the horizontal divider seen in the image above) is the aggregation type you can apply to most fields. If you Group By multiple fields, and there is no limit to the number of fields you group by, Alteryx will calculate every unique combination of the selected fields. This identifies the key fields that the aggregations are calculated over. The first option in the drop-down is “Group By”. Once fields are selected, you decide what action to apply with the “ADD” drop-down (seen in the following image). In this section, you can either select fields individually, select multiple fields by holding the CTRL or SHIFT button or select all fields of a particular type using the “SELECT” drop-down in the top right corner. The above image shows the top of the Summarize configuration. When configuring the summarize tool, there are two parts of the process: the Grouping and Aggregation options. The summarize tool is the primary method for aggregating data sets. The CrossTab is also a requirement for creating a Pivot Table Report Output. The CrossTab tool requires aggregation when you can leverage the pivot activities for your analysis. The Summarize tool will provide the best flexibility and will be the go too for most aggregation activities. To Aggregate data in Alteryx, you will generally be working with two tools, the Summarize tool or the CrossTab tool. Simplifying large data sets to support specific investigations and helping decision-makers to understand the overall trends in their business area are central activities that a data analyst will deliver. The Summary tool is an essential part your Alteryx toolbelt and it is important to spend time to master it.One of the most fundamental actions an analyst can perform is aggregating their data. The summary tool helps you consolidate and analyze data at different levels of granularity which helps provide insights into patterns, trends etc. You can also select more than one summary functions for each field you want to summarize, and Alteryx generates a new table that contains the grouped data and the calculated summary statistics as seen in the example below. In this case we will be doing the sum of profit per region once we have this tool configured and we hit run we should get this output: First and Last: Retrieves the first or last value within each group.Unique: Determines the number of unique values within each group.Count: Counts the number of records or occurrences within each group.Minimum and Maximum: Finds the minimum and maximum values of a numeric field within each group.Average: Computes the mean or average value of a numeric field within each group.Sum: Calculates the sum of a numeric field within each group.Alteryx provides a variety of built-in summary functions, including: In this instance we will group the regions, once the data is grouped, you can specify the summary operations you want to perform on each group. The tool then aggregates the data into groups based on the values in the selected grouping fields. ![]() You can select one or multiple fields as the grouping criteria. When setting up the Summarize tool, you define the fields you want to group by, which are the columns that will determine how the data will be grouped. To begin, we will use this dataset and the summarize tool in order to aggregate the sum profit per region. ![]() It allows you to perform calculations and generate a summary for different groupings within a dataset. In summary, the Summarize tool in Alteryx is used to aggregate and summarize data based on specified grouping criteria.
