Interpretation:
The reason for more usefulness of quantitative observation than a non-quantitative one is to be determined.
Concept introduction:
Observation is the process to watch something or someone. It is the active acquisition of information from a primary source. It also involves the perception and record of data with the help of scientific instruments.
The two types of observations are as follows:
1. Qualitative observations: The observations that can only be observed with the help of senses. Examples of such properties are taste, sight, smell, touch and hear.
2. Quantitative observations: The observations that are made with the help of instruments like rulers, balances, graduated cylinders, beakers, thermometers. Examples of such observations are the length, temperature, weight.

Whether the sun rises in the east is a quantitative or qualitative observation is to be determined.
