The experimental method used to measure the charge of an electron is called the Millikan oil drop experiment. In this experiment, tiny oil droplets were suspended in an electric field and their motion was observed to determine the charge of the electron.
The method of adjustment is a psychological technique used to determine thresholds of perception by allowing participants to directly control the intensity of a stimulus until it reaches a certain level of perception. This method is often employed in psychophysical experiments, where individuals adjust the stimulus until it is barely detectable or reaches a specific criterion. It provides a quick and intuitive way to measure sensory thresholds, but can be influenced by participant bias and variability in responses.
Philosophers, such as Plato, believed that all knowledge could be obtained through pure reasoning, and that there was no need to actually go out and measure anything.
Roger Bacon was a 13th Century philosopher who studied at Oxford, but only accepted theories of astrology and alchemy. He was said to be born in Ilchester in approximately 1214. He promoted the use of experimentation to determine truth. Roger Bacon is credited as being the first modern, experimental scientist. He was the first to formulate and advocate the Scientific Method.

Millikan used the oil drop experiment to measure the charge of an electron.
Modern Mass Spectrometry is the alternative method to measure the charge to mass ratio of an electron.
Robert Millikan discovered the change of electron using the oil drop experiment in 1909. He was able to measure the charge of an electron accurately using this method.
Robert Millikan's method of study involved the famous oil drop experiment to determine the charge of an electron. By carefully observing how electrically charged oil droplets moved in an electric field, he was able to calculate the charge of a single electron. This groundbreaking experiment provided key insights into the fundamental properties of electrons.

which analysis method cannot be applied to experimental research
One method is to use Coulomb's law, which states that the force between two charged objects is proportional to the product of their charges. By measuring the force between the object and a known charge using a sensitive device like an electroscope, the charge of the object can be calculated. Another method involves using an instrument called an electrometer, which can directly measure the charge on an object.
The experimental method allows researchers to establish cause-and-effect relationships by manipulating variables and controlling for confounding factors. This method provides more control over the research setting, increasing internal validity compared to non-experimental methods.
Experimental Method
While the experimental method is ideal for determining cause and effect, the correlational method is still valuable for studying relationships between variables when it's not feasible or ethical to manipulate them. Correlational studies can provide useful information about associations between variables and generate hypotheses for further experimental research.
In this method oil droplets in the form of mist was produced by an atomiser and they were allowed to enter through a tiny hole in the upper plate of electrical condenser.The downward motion of these droplets was viewed through a telescope wid micrometer eye peice. By measuring the rate of fall of these droplets, Millikan was able to measure the mass of oil droplets. Also the air inside the chamber was ionized by passing Xray beams thru it.The electrical charge on these droplets was acquired by collision with gaseous ions...For more information...check in yahoo answers
It is a technique that uses accounting entries to allocate the indirect costs of running the IT department. it has 4 methods: # no charge method # fixed charge method # variable charge method based on resource usage # variable charge method based on volume
