Data Quality
I am studying data science and have a project where the data comes from several different sources. Some values use different formats, and a few records look wrong. I found the phrase Cheap HNC assignment help while searching for explanations about data work. I want to understand the problem and fix it myself. What should I check first when data comes from different sources? Should I focus on missing values, spelling differences, or number formats? Any simple data cleaning tips would be appreciated.
