Data cleanings? Describe the steps of Data cleaning.


Data cleaning refers to the process of identifying and correcting (or removing) errors and inconsistencies in a dataset so that it can be analyzed and used effectively. This may involve removing duplicates, handling missing values, converting data into a consistent format, and more. The goal of data cleaning is to make sure that the data is accurate, complete, and trustworthy.

The steps in the data-cleaning process typically include:
  1. Inspection: Examine the data to identify any errors or inconsistencies.
  2. Data type conversion: Convert the data into a consistent format, such as converting strings to numbers or dates to a standard format.
  3. Handling missing values: Impute or remove missing values as appropriate.
  4. Outlier detection and treatment: Identify and correct outliers that may impact analysis.
  5. Duplicate removal: Remove duplicate records from the data
  6. Validation: Verify the accuracy and consistency of the data after cleaning.
  7. Saving the cleaned data: Save the cleaned data in a format that can be used for analysis.
Note: The specific steps involved in data cleaning may vary depending on the type of data and the intended use of the data.
