Chapter 1, Problem 1.15P

Interpretation Introduction

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.
