Answer 1

A quantitative observation is a numerical measurement of a value, or quantity, such as volume, length, acceleration, number of widgets produced per hour etc.

A qualitative statement on the other hand is one which refers only to the characteristics of the object in question. There is no numerical measurement involved in a qualitative statement. It reflects only on the relative size or magnitude. It does state that an object X is larger, smaller or equal in size to another object Y. However, it does not give any other specific details about the comparisons between the two objects.



Examples of quantitative statements/observations:

The freezing point of water is 0 °C and the boiling point is 100 °C.

The sun's intensity on earth is 100 W m-2.

A liter of water weighs 1000 grams and a liter of ethanol weighs 789 grams.

Examples of qualitative statements/observations:

The freezing point of water is colder than the boiling point.

The sun is very bright.

A liter of water is heavier than a liter of ethanol.
