Why is a quantitative observation more useful than a non-quantitative one? which of the following are quantitative?
(a) the sun rises in the east, (b) a person weighs one-sixth as much on the moo nas on earth, (c) ice floats on water, (d) a hand pump cannot draw water from a well more than 34 ft deep.

Explanation:

An observation that can be counted is known as quantitative observation. On the other hand, an observation that does not contain any numerical data is known as non-quantitative observation.

Therefore, given observations are classified as follows.

(a)  The Sun rises in the east - It is a non-quantitative observation as it cannot be measured.

(b)  A person weighs one-sixth as much on the Moon as on Earth - It is a quantitative observation as it can be measured because we know the mass of moon. Hence, we can find out the weight of person.

(c) Ice floats on water - It is a non-quantitative observation as it cannot be measured.

(d)  A hand pump cannot draw water from a well more than 34 ft deep _ It is a quantitative observation because it is measure that more than 34 ft deep water cannot be drawn by the pump.
