Data cleaning might seem dull and uninteresting, but it's one of the most important tasks you would have to do as a data science professional. Correcting or removing "dirty data" improves the reliability and value of response data for better decision-making. Data cleaning involves the detection and removal (or correction) of errors and inconsistencies in a data set due to the corruption/irrelevance or inaccurate entry of the data.  Incomplete, inaccurate or irrelevant data is identified and then either replaced, modified or deleted.

Incorrect or inconsistent data can create a number of problems which lead to the drawing of false conclusions.  Therefore, data cleaning can be an important element in some data analysis situations.  Having wrong or bad quality data can be detrimental to your processes and analysis. Poor data can cause a stellar algorithm to fail. However, data cleaning is not without risks and problems including the loss of important information or valid data.

Data cleansing is also important because it improves your data quality and in doing so, increases overall productivity. When you clean your data, all outdated or incorrect information is gone – leaving you with the highest quality information. This ensures you do not have to wade through countless outdated documents and allows you to make the most of your project hours
