Question

Quizplus · Accepted Answer

Experimentation involves manipulating one variable at a time in order to study its effect on another variable. Focusing is not a form of quantitative research, but rather a technique used to improve concentration. Trial and error involves repeatedly testing different methods until the desired outcome is achieved. Likert scaling is a method used to measure attitudes or opinions on a scale, but it does not involve manipulating variables. Validation refers to the process of determining the effectiveness or accuracy of a measurement or research tool.
