Science is based upon verifiable evidence. By 'evidence' we mean factual observations other observers can see,weigh, count and check for accuracy. Scientific observation is not the same as just 'looking at things'.
The characteristics of scientific observations are as follows:
1. It is accurate.
2. It is presice.
3.It is systematic.
4.It is recorded.
5.It is objective.
6.They are made by trained observers.
7.They are made under controlled conditions.
8.It is according to time.
This is only a short description of scientific observation. To know more use other websites.
Making an observation of somthing based on its characteristics rather than a number. For example: The rock was hard NONEXAMPLE:There were five rocks
A qualitive observation is an observation of a product of a reaction which cannot be measured numerically, e.g. colour, state of matter. A quantitive observation is an observation which can be measured, e.g. size, volume.
Segregation.
A non-numerical description is a qualitative observation. It uses words to describe qualities or characteristics of an object, event, or phenomenon instead of numerical data.
This is an example of a qualitative observation, which involves describing qualities or characteristics of a specimen without measuring or quantifying them. In this case, noting the presence of 2 antennae on an isopod is a qualitative observation because it describes a visual characteristic without assigning a numerical value.
Qualitative observation.
A qualitative observation is used in chemistry, and is simply observing physical changes.
A test flight is an observation of the flight characteristics of an aircraft.
The two kinds of observation are qualitative and quantitative. Qualitative observation involves descriptions and characteristics, such as color or texture, while quantitative observation involves measurements and numerical data, such as length or weight.
Qualitative observations
Scientific theories are based on observation, usually involve some form of mathematical analysis, and can be tested by experiment or by additional observation.

Observation, data collection and analysis.
An observation that does not involve a measurement is considered to be qualitative. This type of observation typically involves descriptions, characteristics, or properties of objects or phenomena rather than numerical values.
A disclosed observation is when the participants are aware that they are being observed. This reduces ethical issues of consent and privacy but reduces validity due to increased demand characteristics.
It is the scientific research which emphasise on uncovering hidden facts by measurements, observation and experimentation.
