Quantitative observation is usually conducted by sending out surveys questionnaires or polls. You can identify quantitative or qualitative things from statements. Qualitative methods usually make a YES/NO determination of some type, whereas quantitative methods provide a numerical estimate of a quantity, including uncertainties. and then applying certain statistical, objective and pre-determined rules to answer questions like 'what is happening' and 'why is it happening.'. It is widely used in analytical chemistry and the methods that come under this umbrella are used to conduct scientific experiments, and also determine various industrial production aspects. In the experiment P6.5.6.1, the Compton scattering of quanta with the energy E 0 = 667 keV at the quasi-free electrons of an aluminium scattering body is investigated. The hard sciences, physics, chemistry . It uses numerical data and statistical calculations to measure research and draw conclusions. by. 3.) The quantity can be given as a mass, volume, concentration, relative abundance, etc. A theory is a hypothesis that is supported by many experiments. An example of this would be: "This tree has bright green leaves that have soft bumps . A Qualitative Observation is an observation that uses the five senses. It is the active acquisition of information from a primary source. Two types of observations. Here are 7 examples of quantitative observation.
