Data analysis involves cleaning and preparing the data from "summary" of Data Science for Business by Foster Provost,Tom Fawcett
Data analysis involves cleaning and preparing the data before any meaningful insights can be extracted. This initial step is crucial in ensuring the accuracy and reliability of the analysis.
