What is the difference between quantative and qualitative analysis​

Quantitative data can be counted, measured, and expressed using numbers.  Qualitative data is descriptive and conceptual.  Qualitative data can be categorized based on traits and characteristics.

Explanation:

Quantitative analysis involves looking at the hard data, the actual numbers. Qualitative analysis is less tangible. It concerns subjective characteristics and opinions – things that cannot be expressed as a number.
