The experimenter still manipulates the independent variable, but in a real-life setting (so cannot really control extraneous variables). The positive control confirms that the basic conditions of the experiment were able to produce a positive result, even if none of the actual experimental samples produce a positive result. The degree to which this is possible depends on the observed correlation between explanatory variables in the observed data. While other methods of research - case study, correlational, interview, and naturalistic observation - are practiced within fields typically investigated by experimental psychologists, experimental evidence remains the gold standard for knowledge in psychology. controlled methods and the random allocation of participants into controlled and experimental groups. This equivalency is determined by statistical methods that take into account the amount of variation between individuals and the number of individuals in each group. result) of a study. This would make them determine what exactly they are looking for. Observation of the appearance of the moons of Jupiter were slightly delayed when Jupiter was farther from Earth, as opposed to when Jupiter was closer to Earth; and this phenomenon was used to demonstrate that the difference in the time of appearance of the moons was consistent with a measurable speed. All variables, which are not the independent variable, but could affect the results (DV) of the experiment. A confounding variable could be an extraneous variable that has not been controlled.

The term is no longer in existence C. Most psychological topics are not suited to experimental study D.

Define experimental method. Experimental method is more controlled than other methods allowing Psychologists to claim that behaviour is a result of the independent variable. Participants are randomly allocated to each independent variable group.
