Data Detox: Cleaning Up Your Data for Better Results


First let’s see what is Data cleaning, Data wrangling and Data mining?

Data cleaning, data mining, and data wrangling are all related processes that involve working with data, but they have distinct differences.


Data cleaning is the process of identifying and correcting inaccuracies and inconsistencies in a dataset. This can include fixing errors in data entry, removing duplicate records, and standardizing data formats. The goal of data cleaning is to make the data as accurate and reliable as possible for use in analysis or modeling.

There are several steps that are typically involved in the data cleaning process. These include:

  • Inspection: This is the initial step of data cleaning where you inspect the data and identify any problems or issues that need to be addressed. This can include identifying missing data, outliers, and inconsistencies in data formats.

  • Data Cleansing: Once problems have been identified, data cleansing is the process of correcting or removing inaccuracies and inconsistencies in the data. This can include filling in missing data, removing duplicate records, and standardizing data formats.

  • Data Validation: This step is to check the data again after cleansing to ensure that the cleaning process was successful and that the data is accurate and consistent.

  • Data Transformation: This step of data cleaning is used to format the data so that it can be used for analysis or modeling. This can include combining data from multiple sources, creating new variables, and converting data into a format that can be used by a specific tool or software.

  • Data Loading: Finally, the cleaned data is loaded into a database or other storage system for use in analysis or modeling.


Data wrangling also known as data munging, is the process of cleaning, transforming, and organizing data for analysis and modeling. It is an iterative process that involves a combination of manual and automated techniques to prepare the data for analysis.

Data wrangling can include a variety of tasks, such as:

  • Data Gathering: Collecting data from various sources such as databases, spreadsheets, and APIs.

  • Data Assessment: Examining the data to identify any issues such as missing values, outliers, and inconsistencies in data formats

  • Data Cleaning: Cleaning the data by filling in missing values, removing outliers, and standardizing data formats.

  • Data Transformation: Transforming the data by creating new variables, combining data from multiple sources, and converting data into a format that can be used by a specific tool or software.

  • Data Visualization: Visualizing the data to gain insight and identify patterns.


Data mining is the process of discovering patterns and knowledge from large sets of data. The goal of data mining is to extract useful information and insights from data that can be used to inform decision making. Data mining is an iterative process that involves several steps:

  • Data Preparation: This step involves cleaning and transforming the data so that it can be used for analysis. This includes tasks such as filling in missing values, removing outliers, and standardizing data formats.

  • Data Exploration: This step involves exploring the data to gain a better understanding of its characteristics and identify any patterns or relationships that may be present. This can include visualizing the data and computing summary statistics.

  • Data Modeling: This step involves building models to identify patterns and relationships within the data. This can include using techniques such as statistical modeling, machine learning, and data mining algorithms.

  • Evaluation: This step involves evaluating the models to determine how well they fit the data and how well they perform in making predictions.

  • Deployment: This step involves putting the model into production, where it can be used to make predictions or inform decision making.

Data mining can be used to discover patterns and knowledge in a wide range of applications, including business, healthcare, finance, and social media analysis.


So, you get an idea now about Data cleaning, mining and wrangling, let’s see the difference between these three-cleaning process.

In summary,

  • Data cleaning is focused on correcting inaccuracies and inconsistencies

  • Data mining is focused on discovering patterns and knowledge

  • Data wrangling is focused on cleaning, transforming, and organizing data for analysis and modeling.

Thank you for your time! In next vlog we can see how to clean the data step by step.
