What role do operators play in data queries?

Operators are essential components in data queries, primarily because they perform calculations and evaluations on data. They allow users to manipulate and analyze datasets effectively by enabling arithmetic operations, logical comparisons, and various functions. This capability is fundamental to deriving insights, creating statistical analyses, and summarizing data.

For example, arithmetic operators such as addition, subtraction, multiplication, and division help in performing numerical calculations directly on data. Logical operators such as AND, OR, and NOT allow for more complex queries by evaluating conditions, which helps in filtering datasets based on specific criteria.

In contrast, defining the structure of queries generally pertains to query syntax and is not solely reliant on operators. Storing results is more related to database functionalities, and creating new variables usually involves different methods or commands within a data analysis framework, rather than solely using operators.
