Quantitative information is given in terms of numbers. You would usually count or measure something. If you were observing children, an example would be their heights in metres. For cars, you might measure their speeds, or lengths, or masses, but observing their colours would not be quantitative.
There are a number of instruments that can be used in observation. You could use a telescope or microscope for example.
For example, by observing things like interference, which are typical for waves.
Example: i started an experiment and i started to think and ask question about my observing.
You mean quantitative observation, which is observing a measureable value (quantity) of something, for example temperature, voltage, velocity etc. Another form of observation is qualitative observation, which means observing a property of something without measuring a value for it, for example the air might be clear or foggy.
Observing that it has rained every afternoon for the past week, and concluding that it will rain this afternoon as well, is an example of inductive reasoning.
