Types of Data: Qualitative vs Quantitative

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 exact values, and continuous data, which can take any value within a range. The tutorial provides examples and clarifies these concepts, helping viewers understand how scientists collect and categorize data.
