Variable

In Data Science and Artificial Intelligence, a variable is a characteristic or attribute that can be measured or observed and can take different values. Variables can be classified as independent or dependent. Independent variables are those that are manipulated or controlled in an experiment, while dependent variables are the outcomes or results that are being measured. In machine learning, variables are used to represent the features or attributes of the data that are being analyzed. These variables can be continuous or categorical, and their selection and transformation can greatly impact the accuracy and performance of the machine learning model.
