Spreadsheets, such as Microsoft Excel or Google Sheets, are powerful tools widely used for managing and analyzing data. They offer a range of features that simplify basic calculations, making them advantageous for both personal and professional use.

Spreadsheets are designed to handle large volumes of data quickly and efficiently. When you input data into a spreadsheet, you can perform multiple calculations almost instantaneously. This is particularly useful when working with large datasets where manual calculations would be time-consuming and prone to error.

Spreadsheets reduce the risk of human error. With built-in formulas and functions, you can ensure that your calculations are correct as long as the formulas are set up correctly. Functions like SUM, AVERAGE, and IF help automate calculations and reduce the likelihood of mistakes. In this module, we’ll also see how spreadsheets can build graphs to help summarize and visualize data.
