What are the different types of variables?

In programming and statistics, variables are used to store and represent data. There are several types of variables based on the nature of the data they can store. First, there are numerical variables which can hold numeric values such as integers (whole numbers) or floating-point numbers (decimal numbers). Second, categorical variables are used to represent specific categories or groups and can take on a limited number of distinct values. Third, there are boolean variables that can only take two values, typically true or false, representing logical conditions. Lastly, there are string variables which store sequences of characters, such as text or words. Understanding these different types of variables is crucial in programming and data analysis as they determine the type of operations and manipulations that can be performed on the data.
