Statistical functions are used for calculations like averages, sums, counts, or standard deviations, not for directly identifying records based on a specific month.

Logical functions (e.g., IF, AND, OR, WHERE clauses with comparison operators) are used to evaluate conditions and return a boolean result or filter data based on criteria. To flag customers who purchased in January, one would typically use a logical condition like MONTH(PurchaseDate) = 1.

Mathematical functions perform arithmetic operations (e.g., addition, subtraction, multiplication), which are not directly used to identify records based on a month condition.

Date functions are used to extract parts of a date (like MONTH(), YEAR()) or perform date calculations, but a logical function is still required to compare the extracted month to 'January'.
