What is Data Wrangling? 6 Key Steps
Introduction to Data Wrangling
Organizations are churning out raw data each day with their multiple business systems. Decision-makers and company leaders rely on these metrics to steer their operations and enhance their growth. But before extracted data can be put into use, it must be accurate.
Otherwise, the business may miss opportunities, take unnecessary risks, or delay operations. Therefore, organizations have been implementing data wrangling tools to ensure their information is dependable and ready to use.
What Is Data Wrangling?
Data wrangling is the practice of cleansing, restructuring, and enriching raw data. Raw data is complex because it has not been processed or integrated into a system. With data wrangling, these records are transformed into a standard format that helps highlight valuable insights. The process entails consolidating data into one location and rectifying any missing information or errors.
Also known as data munging, data wrangling is considered to be the most time and labor-intensive part of data processing. Data scientists have said that data wrangling takes up approximately 75% of their time to complete. By investing time into the process, teams can focus on ensuring data accuracy. This process is very critical for businesses to perform because it is the only method that makes raw data usable.
Effective data wrangling will help organization leaders foster a bird's eye view of their entire business. It also eliminates instances of data duplication, which would have impacted decision-making. Additionally, since it centralizes disparate data sources, different departments in a business can collaborate and cultivate innovative strategies.
6 Steps for Data Wrangling
Organizations can approach data wrangling in many different ways, from using automation or software to manually entering information into a database. Despite these diverse techniques, the process of data wrangling involves 6 core steps.
Before performing data wrangling, business teams need to fully understand what their data is about. It is also important to know why the business needs the data set and how it will utilize it. This knowledge will help give the team clearer direction on how to organize and analyze the information.
Incoming datasets from multiple sources and systems will arrive in different formats, sizes, and types. Therefore, at this stage, the data must be restructured to a standard format. The data should also be categorized and separated based on its purpose.
3. Data Cleansing
The data cleaning step entails removing duplicates, null entries, and errors in the database. Teams can also further standardize the information. For example, a rule can be implemented to ensure all dates are written in the MM/DD/YYYY format and that all states are abbreviated with 2 letters.
4. Data Enrichment
Enriching data refers to taking existing data and adding supplementary information to derive more insights. For instance, if a retailer wants to learn more about how the effectiveness of their social media ads, they can enrich their sales data with marketing data.
The validation process involves authenticating the reliability, credibility, and quality of the cleaned data. Teams need to make sure that all their data is accurate and that the information was not altered during the data wrangling process.
6. Data Sharing
Once the data is validated, the business team can publish and share their reports. Most commonly, the organization will have a shared file where authorized users can upload data analytics. Depending on the circumstance, a meeting will be held with other departments, employees, and stakeholders to share the new insights.
Common Uses for Data Wrangling
Organizations can use data wrangling for many business functions. The following are the two most common uses.
Data wrangling can help businesses detect and prevent fraud and security risks. It does so by completing the following tasks.
