Logical Expression
In Data Science, a logical expression is a statement that evaluates to either true or false. It is a combination of one or more logical operators, such as AND, OR, and NOT, and one or more operands, which can be variables, constants, or other logical expressions. Logical expressions are commonly used in programming languages, database queries, and statistical analysis to filter, sort, and manipulate data based on certain conditions. For example, a logical expression can be used to check if a value is within a certain range, if a record meets certain criteria, or if a hypothesis is supported by the data. Logical expressions can also be nested, combined, and modified using parentheses, brackets, and other symbols to create more complex conditions.
