A researcher evaluates impression accuracy when using conventional vs digital techniques. Accuracy was assessed by type of finish line, location, and preparation depth. What is the DEPENDENT variable?

✓ A) Impression accuracy is the dependent variable.
The dependent variable (outcome variable) is what is being MEASURED — impression accuracy. The independent variables are what the researcher manipulates or categorizes: impression technique (conventional vs digital), type of finish line, location of finish line, and preparation depth. These are the factors that may influence accuracy. A common mnemonic: the dependent variable DEPENDS on the independent variables.
