Lecture Notes on Spreadsheets

Why Use a Spreadsheet?

• Organization: Spreadsheets use rows and columns to help organize data.
• Data Management: Allows for easy manipulation and management of data.

Structuring a Spreadsheet

• Page Setup: Orientation, size, margins, headers/footers, fit to page options.
• Cells: Coloring, merging, aligning, and adding formulas.
• Freezing Rows/Columns: Ability to freeze rows/columns for easier navigation.
• Data Types: Understanding different data types and how to work with them.
• Text Orientation: Changing text orientation (horizontal/vertical).

Formatting Cells

• Cell Emphasis: Making cells stand out by changing font, style (bold, underline), and size.
• Comments: Add comments to explain data or provide additional information. Insert via 'Insert Comment'.

Conditional Formatting

• Applying Conditions: Set conditions for cell formatting based on criteria (e.g., equal to, greater than, between values).
• Practical Example: Using conditional formatting to highlight important data.

Formulas and Functions

• Basic Operations: Adding, subtracting, dividing, multiplying using formulas.
• Practical Example: Calculating costs in a spreadsheet for a broadband TV, phone package.
  • Formula in cell adds up costs and multiplies them (e.g., line rentals).
• Dollar Function: Formatting numbers as currency by using =DOLLAR(number, decimals).
  • Example: =DOLLAR(20, 5) results in $20.00000.

Cell Referencing

• Relative Cell Referencing: Cell references change when copied to another cell.
  • Example: Dragging a formula across cells automatically adjusts references.
• Absolute Cell Referencing: Cell reference does not change when cells are copied.
  • Example: Useful for situations where you need a constant reference in formulas.

Practical Tips

• Formatting: Use borders and styles for better presentation.
• Shortcuts: Ctrl+B for bold, and other shortcuts for quick formatting.

Queries and Clarifications

• Common Issues: Difficulty in formatting, understanding formulas, and referencing.
• Resources: Use search box feature in spreadsheet software for quick help.

Additional Notes

• Class Interaction: Students encouraged to follow along with practical examples.
• Resource Utilization: Utilize books and resources post-lecture for further practice.
