Experimenter

Fox Talbot’s close friend and fellow experimenter, John Herschel, wrote regularly to Somerville and even helped her photographic investigations to gain some publicity.

He will be a discoverer and experimenter, at least as much as a finisher.

In the study, a child was offered a choice between one small reward (a marshmallow) provided immediately or two small rewards (two marshmallows) if they could wait for about 15 minutes, during which the experimenter left the room and then returned.

The macaws tried to bring the tokens as close as possible to the experimenter but did not transfer the token to the partner, Brucks says.

They enlisted African grey parrots and blue-headed macaws, finding that both species were eager to trade tokens with an experimenter for a nut treat.

She is also a brilliant singer-songwriter and an experimenter with sound.

The experimenter then gave the subject food at two-minute intervals and observed its reaction between feedings.

The vanishes when the experimenter interacts with the quantum state.

Albert G. Ingalls is sometime given credit as co-founder of this movement. citation * Isaac Roberts (1829–1904), early experimenter in astronomical photography.

Assessing possible sender-to-experimenter acoustic leakage in the PRL autoganzfeld.

Before the box is opened, the cat, by nature of its being alive or dead, has information about the state of the apparatus (the atom has either decayed or not decayed); but the experimenter does not have information about the state of the box contents.

But they have a different psychological effect on the experimenter.

Critics pointed out the experiment was flawed as Ownbey acted as both the sender and the experimenter, nobody was controlling the experiment so Ownbey could have cheated by communicating with Zirkle or made recording mistakes.

Crowley, Magick, Book 4, "Liber E" Other items he suggests for inclusion include the physical and mental condition of the experimenter, the time and place, and environmental conditions, including the weather.

Each photon encounters a two-channel polariser whose orientation (a or b) can be set by the experimenter.

Eventually, as the cord continues to unwind, the surface of the water assumes a concave shape as it acquires the motion of the bucket spinning relative to the experimenter.

Fixed-effects models main The fixed-effects model (class I) of analysis of variance applies to situations in which the experimenter applies one or more treatments to the subjects of the experiment to see whether the response variable values change.

For a discussion of Newton's original argument, see citation If the cord is twisted up tightly on itself and then the bucket is released, it begins to spin rapidly, not only with respect to the experimenter, but also in relation to the water it contains.

For an observational science to be valid, the experimenter must know and account for confounding factors.

For example, an experimenter might read a list of 20 words aloud, presenting a new word to the subject every 4 seconds.
