Quantitative observation refers to an observation that deals with the elements and numbers one can measure or count like the dimensions such as width, height, and length. On the other hand, qualitative observation refers to an observation that deals with the descriptions and features, which cannot be measured or counted, however, can be observed by its quality like taste, smell, and color.
