Part 2 : DATA ANALYSIS TECHNIQUES
Learning Some Jargons:
As we delve into the intricacies of data analysis techniques, it’s crucial to familiarize ourselves with some key technical jargon.
This knowledge lays a solid foundation for understanding upcoming explanations. Here are some concepts to get started:
Rows: The horizontal alignment of your data, representing individual observations or entries.
Columns: The vertical alignment of your data, showcasing different attributes or variables.
