The more usefulness of quantitative observation than nonquantitative one should be explained.Among below observations, quantitative observations should be determined. (a) The sun rises in the east (b) A person weighs one-sixth as much on the moon as on earth (c) Ice floats on water (d) A hand pump cannot draw water from a well more than 34 ft deep Concept introduction: The process to watch any object, body or person is known as observation. It also refers to collection of data gathered in any scientific procedure. Observations can either be qualitative or quantitative in nature. Qualitative observations do not involve any kind of measurements or calculations and are determined only with help of various senses like smell, sight, taste, hear and touch. Quantitative observations refer to collection of data based on values, calculations, and numbers. Such observations are generalized in nature.
