The importance of data quality across diverse industries is increasing day by day. Most enterprises rely on data for their business growth, and there arises the need to keep that data error-free. Achieving maximum efficiency depends upon reducing data errors and inconsistencies. Data quality is of utmost importance if your business aims to optimize the working and increase profits by using data. Inaccurate and old data impacts your business outcomes. Want to create a culture around quality data decision-making? You should take a vital data cleaning step, also referred to as data cleansing or data scrubbing.

What is Data Cleansing or Data Cleaning?

Data cleansing is the process of determining and removing inaccurate, incomplete, corrupted, or unreasonable information within a dataset. It can be elaborated as eliminating and perceiving the mistakes available in data to expand its worth. Better data helps in beating fancier algorithms.

Combining multiple sources can give rise to duplicate or mislabeled information. Incorrect data is unreliable. Proper data cleaning can make or break your project. The process of data cleaning may vary from dataset to dataset. However, it is crucial to have a template established to understand whether you are doing it the right way.

What are the characteristics of quality data?

  1. Accurate
  2. Complete
  3. Consistent
  4. Uniform

Different types of data issues

Different types of issues can occur when businesses receive data from other clients, scrape from the web or combine datasets from multiple places. Some example issues are

  1. Duplicate data
  2. Conflicting Data
  3. Incomplete Data
  4. Invalid Data

Important data cleaning techniques

  1. You will have to follow strict guidelines to improve data quality, including mandatory field filling. A proper information input mechanism needs to be followed.
  2. A unique reference number or URN and data consistency also play a vital role in accurately managing information. URN helps in tracking changes and helps significantly in data cleaning.
  3. Cleaning is the best practice if done in small volumes. Ample downtime will result in breakage and heavy loss of information.
  4. Capturing all the core fields should be done separately.
  5. Careful selection of data cleaning tools and techniques is mandatory.
  6. There are different new and better tools to manage big data and all the complexities accompanied.

Businesses can also outsource their data cleaning tasks to a reliable data cleaning company considering the security factor.

What are the steps involved in the Data Cleaning Process?

Data cleansing is a tedious task, but when done in a proper way can help your businesses grow to a greater extent. Here are a few data cleaning steps that can help you move forward with the process.

  • Step 1 – Remove irrelevant or duplicate observations

    Data collection usually gives rise to duplicate observations. Unwanted observations, including duplicate and irrelevant comments, should be removed. Statements that do not fit into the specific problem when analyzed are irrelevant. Make your analysis more efficient to minimize distraction from your primary target and create a performing dataset. Deduplication is one of the significant areas to be considered in the data cleaning process.

  • Step 2 – Care for your missing information

    Many of the algorithms do not accept missing values. It would help if you dealt with missing data properly. Dropping observations with missing values will result in losing information. Better input missing values based on other comments. But there is a chance of losing data integrity because you are operating on assumptions. So decide how to resolve this missing data issue and move forward.

    An appropriate way to handle your missing data for categorical features is to label them as “missing.” In case of missing numeric data, flag and fill the values.

  • Step 3 – Fixing structural errors

    There are chances of getting strange naming conventions, incorrect capitalization, and massive typos when transferring or measuring data. These are the inconsistencies that can cause mislabeled categories or classes. These are the structural issues that need to be fixed in the data cleaning process.

  • Step 4 – Unwanted outliers need to be filtered

    There might be one-off observations that do not appear to fit within the data. Removing an outlier will help enhance the performance of the statistics you are working with. If an outlier proves to be irrelevant for analysis, consider removing it to improve your model’s performance.

  • Step 5 – QA

    After the completion of the data cleaning process, you should be able to answer the following questions

    1. Does your data make sense now?
    2. Does the information follow the appropriate rules for its field?
    3. Does it prove or disprove your working theory?
    4. Were you able to find trends in the data to form your next idea?

What are the benefits of the data cleaning process for business enterprises?
