Determinant

Definition

Determinant means a factor that decisively settles an outcome, especially when many possible causes are present. Exertion, by contrast, means the application of effort or pressure, without guaranteeing any outcome. So, determinant focuses on the crucial factor that makes the final difference. Exertion focuses on the act of trying or pushing, regardless of success. In other words, a determinant is the key factor that seals the result; exertion is simply the effort put in, which may or may not lead to a result.

What it describes

A researcher wants to know why some students succeed in school while others fail. She studies many factors: family income, teacher quality, hours of sleep, and access to books. After careful analysis, she finds that the single most important factor is parental involvement. Without it, even the best schools and rich families could not guarantee success. This one factor makes the biggest difference. What is parental involvement in academic success? It is a determinant of success.
