Lesson notes

2.1 Spreadsheet Software (MS Excel / Google Sheets): Data Analysis and Visualization Concepts: Understanding the structure of a spreadsheet (rows, columns, cells), data types (numeric, text, date), formulas (using operators like +, -, , /, ^), functions (SUM, AVERAGE, MAX, MIN, COUNT, IF, VLOOKUP, HLOOKUP), cell referencing (relative, absolute, mixed), charts (bar, line, pie, scatter), pivot tables.

Explanation: Spreadsheets are powerful tools for organizing, analyzing, and visualizing data. In a South African business context, they can be used for budgeting, sales forecasting, inventory management, and tracking customer data. Formulas are mathematical expressions that perform calculations. Functions are pre-defined formulas that simplify complex calculations. Cell referencing allows you to use data from other cells in your formulas. Charts provide a visual representation of data, making it easier to identify trends and patterns. Pivot tables are used to summarize large datasets and create meaningful reports.
