Inputvariabel

Inputvariabel, typically translated as input variable in English, is a variable that holds data supplied to a system, function, model, or process as input. It represents the independent data that influences outcomes and is provided by users, sensors, data sources, or configuration. In practice, inputvariables are used to parameterize operations, control behavior, or initiate computations.

In programming, an inputvariabel holds values passed into a function, procedure, or module. For example, in a function that computes a sum, the parameters a and b are inputvariables. In applications, variables such as userName, age, or filePath store inputs collected from a user or from external sources.

In statistics and data science, inputvariables are the features or predictors used to estimate or explain a target variable. They can be numerical, categorical, or transformed data. The term is closely related to the independent variable, which is often the input dimension in a model described by y = f(x). Data preparation steps—such as handling missing values, encoding categories, and normalization—aim to make inputvariables suitable for modeling.

Key distinctions include inputvariables (inputs) versus the output variable (dependent variable) and versus internal state variables used within a system. Understanding the role and quality of inputvariables is essential for accurate modeling, debugging, and reliable software behavior.
