What Are The Root Causes Of Data Issues
Data issues arise due to technical problems such as:
- Synchronization issues: When data is not appropriately shared between two systems, it may also cause a problem. For example, a banking sales system captures a new mortgage but fails to update the banks marketing system, then the customer may confuse if they get a message from the marketing department.
- Software bugs in data processing applications: Applications can write data with mistakes or overwrite correct data due to various bugs.
- Information Obfuscation by users: It is the concealment of data by purpose. People may give incomplete or incorrect data to safeguard their privacy.

Challenges Of Data Cleaning
Image source: Preact CRM
Data cleaning, though essential for the ongoing success of your organization, is not without its own challenges. Some of the most common include:
- Limited knowledge about what is causing anomalies, creating difficulties in creating the right transformations
- Data deletion, where a loss of information leads to incomplete data that cannot be accurately filled in
- Ongoing maintenance can be expensive and time-consuming
- It is difficult to build a data cleansing graph to assist with the process ahead of time
Data Sets For Data Cleaning Projects
Sometimes, it can be very satisfying to take a data set spread across multiple files, clean it up, condense it all into a single file, and then do some analysis. In data cleaning projects, it can take hours of research to figure out what each column in the data set means. It may turn out that the data set youre analyzing isnt really suitable for what youre trying to do, and youll need to start over.
That can be frustrating, but its a common part of every data science job, and it requires practice.
When looking for a good data set for a data cleaning project, you want it to:
- Be spread over multiple files.
- Have a lot of nuance, and many possible angles to take.
- Require a good amount of research to understand.
- Be as real-world as possible.
These types of data sets are typically found on websites that collect and aggregate data sets. These aggregators tend to have data sets from multiple sources, without much curation. In this case, thats a good thing too much curation gives us overly neat data sets that are hard to do extensive cleaning on.

Data.world is a user-driven data collection site where you can search for, copy, analyze, and download data sets. You can also upload your own data to data.world and use it to collaborate with others.
All of the data is accessible from the main site, but youll need to create an account, log in, and then search for the data youd like.

There are some great free tools available that can make this part of data science less of a chore. Cindy and I scoured the Internet to put together the following list of powerful wrangleware.
1. Tabula
Ever had to convert a table data embedded in a PDF into a spreadsheet? There should be a better way to do this than pasting raw PDF into Excel, and then spending hours forcing the messy data into the right columns. The very smart Tabula does this task automatically. Its available as a Github project. Its great for marketers, data journalists, financial analysts, as well as data scientists.
2. OpenRefine
OpenRefine was a Google code project that now lives on as open source software. Its friendly GUI is very good at letting you describe and then manipulate data. It was meant for non-data scientist to use directly, but it has a powerful set of programmable expressions for more sophisticated tasks.
3. R packages
R is an important programming language for data scientists. It has serious support of statistical and probability functions, and excels at handling slabs of numeric data, unlike general purpose languages. R can be extended through a series of libraries or packages so you dont have to reinvent the data wrangle wheel. R programmers have used the functions in the popular dlpr and tidyr packages to help them tame unruly data. Theres a good overview of how to wrangle with R, courtesy of the folks at ComputerWorld.

The Best Solution For Your Business
When choosing a data cleansing solution, consider your budget, your objectives, the state of your data, and the potential for improved sales efficiency.

What Are The Benefits Of Data Cleaning
Better quality data impacts every activity that includes data. Almost all modern business processes involve data. Subsequently, when data cleaning is seen as an important organizational effort, it can lead to a wide range of benefits for all. Some of the biggest advantages include:
- Streamlined business practices: Imagine if there are no duplicates, errors, or inconsistencies in any of your records. How much more efficient would all of your key daily activities become?
- Increased productivity: Being able to focus on key work tasks instead of finding the right data or having to make corrections because of incorrect data is essential. Having access to clean high-quality data, with the help of effective knowledge management can be a game-changer.
- Faster sales cycle: Marketing decisions depend on data. Giving your marketing department the best quality data possible means better and more leads for your sales team to convert. The same concept applies to B2C relationships too!
- Better decisions: We touched on this before, but its important enough that its worth repeating. Better data = better decisions.
These different benefits in conjunction generally lead to a business that is more profitable. This is not only because of better external sales efforts but also because of more efficient internal efforts and operations.
