The scientific method
The most important characteristic is that it be objective, i.e., free from bias.
Inferences should be based on objective observation and logical reasoning.
A qualitative observation is used in chemistry, and is simply observing physical changes.
A qualitative observation merely indicates that the subject possesses a certain quality, for example "this water is salty". A quantitative observation takes a measurement of the quality, for example "this salty water has a concentration of 10% salt".

The observation of an objective from an observation post (OP)
This is an objective observation as it describes the events that took place without adding any personal bias or interpretation. It states the facts of the situation without assigning any subjective opinions.
The Scientific Method
A subjective observation is an observation that relies on personal perception. Because it is not based on measurable, objective fact, subjective observations vary from person to person.
Objective observation refers to the process of gathering information using factual, measurable data without personal bias or interpretation. It involves recording data or information based on what can be directly observed, measured, or documented.
A qualitative observation is an observation that describes the properties of something by using our five senses (touch, taste, smell, see, and hear).
Indirect observation
Observation is the act of noting or perceiving something using the senses, while interpretation involves assigning meaning or significance to those observations based on one's understanding, beliefs, or context. Observation is objective and based on direct sensory input, while interpretation can be subjective and influenced by personal biases or experiences.
"the isopod has 2 antenae" is an example of which kind of observation?
Qualitative observation focuses on qualities and characteristics, such as color, texture, or smell, while quantitative observation involves measurements and numerical data, such as length, weight, or temperature. Qualitative observations are descriptive and subjective, while quantitative observations are objective and measurable.
