hich of the following is a unique characteristic of a true experiment?Multiple Choicepredetermined assignment of participants to controlobservation of one person, often over a long period of timecausal relationships between variablesexperimental manipulation of a predicted cause, the independent variable
Solution
The unique characteristic of a true experiment is the experimental manipulation of a predicted cause, the independent variable. This means that the researcher has control over the independent variable and can manipulate it to observe its effect on the dependent variable, thereby establishing a causal relationship. This is what sets true experiments apart from other types of research designs.
