Data Preprocessing Vs. Data Wrangling

  • Data Preprocessing is performed before Data Wrangling
  • Data Preprocessing data is prepared exactly after receiving the data from the data source.
  • In this initial transformations, Data Cleaning or any aggregation of data is performed. It is executed once.
  • It is the concept that is performed before applying any iterative model and will be executed once in the project.
  • Data Wrangling is performed during the iterative analysis and model building.
  • This concept at the time of feature engineering.
  • The conceptual view of the dataset changes as different models is applied to achieve good analytic model.
