What Is Data Cleansing, Why Is It Important, And How Can You Do It

What is data Cleansing?

Data Cleansing— also known as data cleansing or data scrubbing this process involves modifying or removing inaccurate, duplicate, incomplete, incorrectly formatted, or corrupted data within a dataset. While deleting data is part of the process, the ultimate goal of data cleaning is to make a dataset as accurate as possible. This might require fixing spelling and syntax errors, identifying and deleting duplicate data points, correcting mistakes like mislabeled or empty fields, and standardizing how data is entered or combined from multiple sources. Improve your data accuracy and make informed decisions with data cleansing.

Why is data cleaning important?

In the world of business, reliable data is key to success. But what happens when your decisions are based on inaccurate or redundant information? Data cleansing is often overlooked, but it's just as important as data collection. By identifying and rectifying errors within datasets, you can ensure that you have the most accurate insights. This will not only boost productivity and improve campaign effectiveness, but also increase your ROI. Don't let unreliable data hold you back - prioritize data cleansing for success.

How to Clean Data

How to Clean Data

Step 1: Remove Duplicate and Irrelevant Entries

Having a large database is not enough; it's the quality of data that counts. Duplicate or irrelevant data can cloud your insights. Inconsistency in data entry and multiple channels for contact information are two common causes of duplicates. Keep your data clean and accurate.

Step 2: Fix Any Structural Errors

Structural errors refer to typos, unusual naming conventions, inconsistent abbreviation, capitalization, or punctuation, and other errors that usually result from manual data entry and lack of standardization. For example, “Not Applicable” and “N/A” may appear as separate categories but should be analyzed as the same.

Fixing any structural errors makes your dirty data look cleaner. All information becomes consistent and follows a standard format. This reduces the chance that some pieces of data may fall under the wrong category or otherwise not be properly used.

Step 3: Address missing Data.

Missing data is a common problem in data analysis, but it doesn't have to be a roadblock. There are a few ways to tackle this issue, such as removing entries with missing values, inputting missing values based on other information, or flagging the data as missing. While none of these solutions are perfect, they will help to minimize the negative impact on your data analysis. Remember, missing data is inevitable, but with these approaches, you can still draw valuable insights from your datasets.

Step 4: Keep your data fresh.

Did you know that 30 percent of company data becomes outdated each year? This can lead to missed opportunities and wasted resources. However, there are ways to keep your data fresh. Implementing parsing tools can scan all incoming emails and update contact information as it comes to hand, ensuring that your central database is instantly updated. Additionally, deleting bounced or opted-out email addresses can not only help keep your data fresh but also keep you out of spam folders. Take the necessary steps to keep your data current and maximize your success!

Step 5: Standardize data entry

Cleaning your data should be an ongoing process, not a one-time activity. Routine data cleaning ensures an accurate and up-to-date data set, as errors can occur anytime. Standardizing data processes can also reduce the number of errors. Setting rules for data input and collection types can help increase accuracy and confidence in your data.
