Data Cleaning explained

This term is also referred to as data scrubbing or data cleansing. It is the process of identifying and correcting issues, if any.

This technique is also used to remove the unfixable facts and clean them appropriately. Issues usually occur due to human error or combining facts from diverse resources.

Garbage in and garbage out is the general principle on which this cleansing technique is based.

Data Cleansing Techniques

Different cleaning methods and techniques are required for each set. Here we will go through some of the common issues which are likely to arise when carrying out the process. Your objectives play a major role in starting with the process. What do you want to gain from this? These things will help you set some standards and rules before inputting your information.

Let’s go through some of the effective techniques as follows

  1. Removing duplicates

    • Your dataset will have duplicate entries when it is collected from different sources.
    • The reason might be human error when the information is input by a person
    • Duplicates will confuse information and make them hard to visualize and read.
    • Therefore the best method is to remove them in the right way.
  2. Unwanted data removal

    • Irrelevant facts will slow down and confuse the analysis you want to carry
    • Before you start the process, decipher what is relevant and what is unnecessary
  3. Data enrichment with capitalization

    • You need to make sure that the text within your information is consistent
    • A mixture of capitalization can create problems for different categories
    • Sometimes capitalization can change the whole meaning of your information.
  4. Converting types of information

    • Numbers need to be converted while carrying out the process of cleaning.
    • Numbers sometimes are input as text, but to get processed, they need to appear as numerals
    • However, algorithms cannot perform mathematical equations if they are classed as a string.
  5. Clear Formatting data process

    • Facts taken from different sources are usually in different document formats.
    • This makes your information incorrect and confusing.
    • Removing that formatting is necessary as it is applied to your documents.
  6. Error fixing

    • Typo errors can be misleading and need to be carefully removed.
    • Quick spell check can help in avoiding such mistakes usually.
    • Punctuation marks play a vital role in email addresses, and mistakes can lead to sending unwanted emails
    • Other errors might include formatting inconsistencies.
  7. Translation

    • Information consistency also depends upon the language you are using
    • Make sure you use the same language in the dataset
    • If everything is not in the same language, you need to translate everything into one language.
