Quizplus · Accepted Answer

An experiment involves manipulating one variable (independent variable) to observe its effect on another variable (dependent variable). This type of controlled test allows researchers to draw cause-and-effect relationships between variables. Correlational studies examine the relationship between variables without manipulating them, while control condition refers to the absence or neutral condition used as a comparison in an experiment. Single-blind studies involve participants who are unaware of whether they are in the experimental or control group.
