What is the use of Imputation tool in Alteryx

This recipe explains what is the use of Imputation tool in Alteryx

Recipe Objective:-What is the use of Imputation tool in Alteryx.

Step 1:-

Open Alteryx Designer software.Here New workflow1 is by default available.

Step 2:-

Now go to the Favorite tab or IN/OUT tab where we can see a tool named as "INPUT DATA".

Step 3:-

Drag the INPUT DATA tool on the below side in the New Workflow1.Now go to the Configuration pane/window and click on the drop down available to connect a file or database.

Master the Art of Data Cleaning in Machine Learning

Step 4:-

After this it will redirect us to the data connection window, here we have to click on files option, then click on select file option,it will then ask us to select a file from the folder, here we have selected a file named as"Coffee Chain Sales".Then select "Imputation" sheet from file and click on Ok.

Step 5:-

Then click on Run button or press CTRL+R, In the results workflow data will be displayed where null values can also be seen in Coffee sales column/field.Drag the Imputation tool from the Preparation tab and connect it with the INPUT DATA tool.

Step 6:-

Then go to the configuration pane/window, Select the Field to impute as "Coffee Sales", Select "Null" from Incoming values to replace, from Replace with value option, select the "Average" option, then click on run button so all the null values will be replaced with average and results workflow will be available.If we want to represent it in new column/field, select option as "Output imputed values as a separate field".
