Basic Computations in MS Excel - JSS3 Computer Studies Lesson Note

Microsoft Excel excels in performing various computations and calculations, making it a powerful tool for data analysis. One fundamental operation is the Basic Arithmetic Functions, including addition, subtraction, multiplication, and division. Users can perform these operations on individual cells or entire ranges, providing quick and accurate results. Excel supports the use of Formulas, which are expressions that perform calculations on data in the cells. Common functions include SUM, AVERAGE, MAX, and MIN, which help summarize and analyze datasets effortlessly.

The AutoSum Function simplifies the process of adding up a column or row of numbers by automatically generating the sum formula. Excel's Absolute and Relative Cell References are crucial for copying formulas efficiently. Users can lock specific cell references (absolute) or allow them to adjust based on the copied location (relative), providing flexibility in formula replication. The IF Function is a logical function that allows users to apply conditions to data, facilitating decision-making in spreadsheets. Moreover, Excel's Data Tables enable users to explore different input values and see how they affect the results of formulas, which is particularly useful for sensitivity analysis.
