ywaarde

Ywaarde is a Dutch term used to refer to the value of the dependent variable y in mathematical, statistical, and data-analytic contexts. It denotes the vertical coordinate in a Cartesian plot and represents the outcome or response in a relationship between variables. The term is common in educational materials, data reporting, and informal discussions of graphs and models.

Definition and usage. In a function written as y = f(x), the ywaarde for a given x equals f(x). In data sets, each observation has an x-value (the independent variable) and a ywaarde (the dependent variable). In statistical modeling, observed y-values are often compared with predicted or fitted values, commonly denoted ŷ, with residuals measuring their differences.

Examples. If y = 3x + 2 and x = 4, the corresponding ywaarde is 14. On a scatter plot, points have coordinates (x, ywaarde). In a regression context, the line provides predicted y-values ŷ for each x; the actual ywaarde may differ, producing residuals such as y − ŷ.

Notes. The spelling and usage can vary, and the term is not a formal mathematical symbol in all contexts. Nevertheless, ywaarde serves as a natural-language reference to the value of the dependent variable in diagrams, calculations, and reports, spanning mathematics, statistics, and data visualization.
