Final answer:
Parametric analysis examines the range of values of the independent variable to determine its effect on the dependent variable, crucial in experimental design in psychology.
Step-by-step explanation:
The question pertains to parametric analysis, an approach often used in the field of psychology and experimental design to understand the impact of different levels of an independent variable on a dependent variable. A parametric analysis B) examines the range of values of the independent variable. In other words, it looks at how different levels of the independent variable affect the dependent variable. In an ideal experiment, such as the hypothetical psychologist's study regarding the size of tableware and its influence on food consumption, the independent variable would be the size of the tableware and the dependent variable would be the amount of food consumed. The integrity of an experimental study is paramount, often including control groups and randomization to ensure results are due to the manipulation of the independent variable and not other factors.
