Question

What do you mean by observation?

Answer 1

Hint :The active gathering of information from a primary source is known as observation. Observation in living creatures makes use of the senses. Observation in science may also refer to the perception and recording of data using scientific tools. The word can also apply to any information gathered during a scientific endeavour. Observations can be qualitative, in which just the existence or absence of a quality is noted, or quantitative, in which the observed phenomena is given a numerical value by counting or measuring.

Complete Step By Step Answer:
The necessity for reproducibility necessitates the ability to compare observations made by various observers. Because human sense perceptions are subjective and qualitative, recording and comparing them is challenging. The use of measurement evolved to allow for the recording and comparison of observations made by various persons at different times and locations. Measurement is the process of comparing a phenomena to a standard unit through observation. The standard unit might be an artefact, procedure, or concept that any observers can reproduce or share. The number of standard units equivalent to the observation is tallied in measurement. Human senses are limited, and perceptual mistakes such as optical illusions can occur. Weighing scales, clocks, telescopes, microscopes, thermometers, cameras, and tape recorders were developed to aid human observation abilities, while indicator dyes, voltmeters, spectrometers, infrared cameras, oscilloscopes, interferometers, geiger counters, and radio receivers were developed to translate events that are not visible to the senses into perceptible form. One issue that arises in many scientific areas is that observation might have an impact on the process being watched, resulting in a different conclusion than if the process were not seen. This is referred to as the observer effect.

Note :
The human senses do not work like a video camera, capturing all observations objectively. Human perception is based on a complicated, unconscious abstraction process in which selected elements of incoming sensory input are stored while the rest is discarded. What is preserved and what is discarded is determined by an internal model or picture of the world, referred to as a schema by psychologists, that is formed throughout the course of our life.
