Today we are releasing the data cleaning project for Tableau Prep. This is the fourth of ten projects that focus on data cleaning and analytics. Tableau Prep is a nice option to have available for your students because it runs on both a Mac and Windows operating system.  Keep reading to learn how to request this first beginner level project that uses Tableau Prep for data cleaning and Tableau for data analytics.

A key step in data analytics is getting the data ready for use – in fact, this step can take more time and effort than the analysis of the data. This brand-new Tableau Prep project focuses on the data cleaning aspect of data analytics and is appropriate for introductory accounting – but could be adapted to any accounting class. This Google Sheets case is designed to guide students through data cleaning and data analysis with step-by-step tutorial videos.

KAT Concession Supply is a fictitious company that supplies food, paper products, and other items to fairs, amusement parks, and other organizations. Information in the KAT Concession Supply data sets includes information about its sales over a three-year period. The data from KAT Concession Supply has errors and irregularities in it and it must be cleaned so that an interactive dashboard about its operations can be prepared. This Tableau Prep project is classified as beginner because it takes less than an hour to complete the entire project and the steps are pretty basic.

Complete step-by-step tutorial videos and an instructor guide are available to make project adoption easy and painless in accounting courses. The project is available at no cost for instructors to use in their classes.
