Data Cleaning Methods Power BI vs. Rattle/R for Data Cleansing
Why We Need Clean Data: In its current form, the bank customer data set is yielding questionable results after analysis. Without clean data, any further attempts of analysis will be unreliable. Issues In Data Set: The current data set has many issues which require data cleaning methods including: - Missing/Blank Data - Misspelled Data/Inconsistent Spellings - Special Characters/Inconsistent Formatting - Statistical Outliers/ Duplicate Data - NULL and N/A Values Importance of Data Cleaning: Clean Data is crucial to the accurate outcome of data analysis, and decision- making. Unclean data can waste time, resources and productivity. This data must be clean so we can make predictions on who is likely to use Term-Deposits Need For Clean Data
POWER BI • To clean data in Power BI, we use the Power Query Editor • Use the “Transform Data” Tab • Power Query Editor is a “one-stop-shop” • Easy and Intuitive

RATTLE/R • Use of Rattle requires some coding • Use the “Transform” Tab to clean data • Integration with R for custom scripting • Complex, but Robust
POWER BI POWER BI RATTLE/R 01 02 03 04 01 02 03 04 User-friendly interface that excels in exploration, visualization, and reporting. Much greater learning curve if not familiar with R syntax. Can be easily used for simple data cleaning, but may be limited due to fixed programming. Suitable for simple or complex data cleaning tasks due to custom scripting through R. More ready-to-use tabs and tools in the “Transform Data” tab. “Transform” tab had limitations on scope of use. R custom scripting was required to fully clean data set. Harder to find missing, blank, or N/A data due to lack of exploration tools. “Summary” and “Exploration” tabs made it easy to find issues in columns.
