2. Excel – Lesson 4 Summarizing Data with Functions A function is a predefined formula that performs a calculation. When you apply a function to specific data, you eliminate the time involved in manually constructing a formula. Using functions ensures the accuracy of the formula’s results.

3. Excel – Lesson 4 Summarizing Data with Functions A function consists of a function name, function arguments, and specified syntax. The arguments are enclosed in parentheses in the formula. – This lets Excel know where the formula begins and where it ends. Depending on the function, an argument can be a constant value, a single-cell reference, a range of cells, or even another function. – If a function contains multiple arguments, the arguments are separated by commas.
