During this process , researchers would use their observational skills and record every notable occurrence that happen to the variables.
The focus on this process is simply to add all relevant data without making any analyzation. That process come later on after the researchers started to change the variables in order to see whether it would create a correlation.
The correct answer is option A, that is, collecting data.
At the time of collection or observation, the researchers would utilize their observational skills and note every remarkable happening that takes place to the variables. The aim of the procedure is basically to supplement all the information without making any kind of assessment.
