This method of observation views research variables in terms of quantity hence; it is usually associated with values that can be counted such as age, weight, volume, and scale. Examples of quantitative observation include age, weight, height, length, population, size and other numerical values while examples of qualitative observation are color, smell, taste, touch or feeling, typology, and shapes. The responses provide a comprehensive perspective on each individuals experiences, which are then compared with those of other participants in the study. Quantitative observation defines research data based in terms of quantity hence, it utilizes statistical parameters for measurements.
