A researcher records observable data when a group of researchers is most likely to conduct a meta-analysis if an experiment has.
The recording of observable data involves studying of the spontaneous behavior of participants in natural surroundings. The researchers can simply record what they see in whatever way they want.Observation means to study a subject under all possible conditions and situations.
Recording a data ensures the preservation of information in a very systematic way. A record is a collection or segregation of fields typically in fixed number and sequence for future reference. If the data to be recorded is of an experiment than the experiment is performed several times and data is recorded every time and after that the average is taken out. And the last final reading is the final result.
