Existing fields and new fields

Now that you've created targeted subsets of the original data by applying filters to obtain data that has a year built, gross square feet, a sale price greater than $100,000 and a unique address, additional research can be applied.

Your supervisor would like to format the RecordID field by adding leading zeroes to match the existing field within a database. They are also interested in finding the highest sale price per gross square foot of this updated property dataset.

The Formula tool is a perfect solution for updating the existing RecordID field, and creating a new calculated field of "Price per Sq Ft"!

Expand your data preparation skills in Alteryx by uncovering ways to filter data and write expressions to create subsets of data. Basic and chained filters will be explored, along with custom filters, to get right to the data you need. You’ll learn best practices in writing expressions, including understanding the differences between AND and OR statements, along with helpful tips for correct syntax.

Exercise 1: Filtering and Using Expressions Exercise 2: Understanding filter expressions Exercise 3: AND, OR and more!Exercise 4: Basic and chained filters Exercise 5: Custom filters and expressions Exercise 6: Combining sort and unique tools

Go further into the layers of data preparation by diving deeper into various formulas and how they can be quickly applied in Alteryx. Discover the wealth of pre-structured formulas available and ready to use in the Formula tool, along with techniques for writing efficient expressions based on data types. You’ll learn the difference between length and position-based formulas and methods to update and create new fields.

Explore the processes of sampling and summarizing your data, which are essential aspects of data preparation. You’ll learn many options for sampling data, such as finding the top 10 records or obtaining the first N percentage of data, and much more with the Sample tool. You’ll then expand your knowledge of summarizing data using numerical methods like sum, average, and median, as well as string functions like grouping by specific fields hierarchically in the Summarize tool.
