Data Types: Qualitative vs Quantitative Insights

The video tutorial explains the differences between qualitative and quantitative data. Qualitative data involves non-numeric descriptions and subjective impressions, while quantitative data includes numeric values obtained through counting or measuring. Quantitative data is further divided into discrete data, which has specific values, and continuous data, which can take any value within a range. The tutorial provides examples and clarifies these concepts to help viewers understand the types of data scientists collect and analyze.
