-# Pivot Tables Activities: Step-by-Step Guide
-
-## 📋 Overview
-This guide will walk you through completing the pivot table activities using LibreOffice Calc. You'll learn how to create pivot tables, analyze data, and troubleshoot common issues.
-
-## 🎯 Activities Checklist
-- **Activity 1:** Manual Data Analysis Challenge (10 minutes)
-- **Activity 2:** Create Your First Pivot Table
-- **Activity 3:** Recreate Example Pivot Tables (1C and 1B)
-- **Activity 4:** Advanced Analysis with Data Set 2
-
-## 🚀 Getting Started
-
-### Step 1: Download and Open the Spreadsheet
-1. Download the file: Pivot tables and advanced filtering (XLSX)
-2. Open the file in LibreOffice Calc
-3. Make sure you're using LibreOffice version 6.0 or higher
-
-## 📊 Activity 1: The Manual Challenge (Learning Hook)
-
-### What to Do:
-- Go to the Data 1 worksheet tab
-- DO NOT USE PIVOT TABLES for this activity
-- Manually calculate for each actor:
-  - How many episodes they appeared in
-  - Their total earnings
-
-### Step-by-Step:
-1. **Sort the data:**
-   - Select columns A-F (including headers)
-   - Go to Data → Sort
-   - Sort by "Surname" (Column A)
-
-2. **Count episodes manually:**
-   - For each surname, count how many rows appear
-   - Write this in a new column or separate sheet
-
-3. **Sum earnings manually:**
-   - For each actor, add up all values in the "Earnings" column
-   - Double-check your calculations
-
-### ⏱️ Time: 10 minutes
-**Reflection Questions:**
-- How many potential errors did you make?
-- How tedious was this process?
-- How would this scale with 1,000 rows of data?
-
-## 🔧 Activity 2: Create Your First Pivot Table
-
-### Step-by-Step Instructions:
-
-#### Step 1: Select Your Data
-- Go to Data 1 sheet
-- Select all data including headers (cells A1:F31)
-- Click cell A1
-- Hold Shift and click cell F31
-- Or press Ctrl+A to select all
-
-#### Step 2: Open Pivot Table Wizard
-- Go to Data → Pivot Table → Create
-- Select Current selection
-- Click OK
-
-#### Step 3: Configure Your Pivot Table
-- Drag and drop fields in the layout area:
-  - Drag "Surname" to ROW FIELDS
-  - Drag "Episode" to DATA FIELDS
-  - Drag "Earnings" to DATA FIELDS
-- Configure calculations:
-  - For "Episode": Double-click it → Select Count
-  - For "Earnings": Double-click it → Select Sum
-- Final layout should show:
-  
-  ```
-  Rows: Surname
-  Data: Count - Episode
-  Data: Sum - Earnings
-  ```
-
-#### Step 4: Place the Pivot Table
-- Choose New worksheet
-- Click OK
-- Your pivot table will appear on a new sheet
-
-#### Step 5: Verify Results
-- Compare your pivot table results with the example in Pivot table 1A
-
-## 📈 Activity 3: Recreate Example Pivot Tables
-
-### Task 3A: Recreate Pivot Table 1C
-1. Start fresh from Data 1
-2. Create a new pivot table
-3. Try this configuration:
-   - Rows: First Name
-   - Columns: Role
-   - Data: Count - Episode
-   - Data: Average - Earnings
-
-### Task 3B: Recreate Pivot Table 1B
-1. Create another new pivot table
-2. Try this configuration:
-   - Rows: Role
-   - Columns: Season
-   - Data: Sum - Earnings
-   - Filter: Surname (optional)
-
-### 💡 Tips:
-- Right-click on any cell in the pivot table → Refresh to update
-- Double-click any field in the layout to change its calculation
-- Drag fields between areas to experiment
-
-## 🎓 Activity 4: Advanced Analysis (Data Set 2)
-
-### Step 1: Navigate to Data Set 2
-- Go to Data 2 worksheet
-- Familiarize yourself with the columns:
-  - Subject, Session Type, Completed, etc.
-
-### Challenge 4A: Subject Completion Analysis
-1. Select all data in Data 2
-2. Create a new pivot table
-3. Configure:
-   - Rows: Subject
-   - Columns: Completed (Yes/No)
-   - Data: Count - Completed
-
-### Challenge 4B: Detailed Session Analysis
-1. Create another pivot table from Data 2
-2. Configure:
-   - Rows: Subject
-   - Columns: Session Type
-   - Data: Count - Session Type
-   - Data: Count - Completed
-3. Hint: You might need to add "Session Type" twice to get both calculations
-
-## ⚠️ Troubleshooting: Cells Not Auto-Recalculating
-
-### Problem: Pivot table doesn't update when source data changes
-
-#### Solution 1: Manual Refresh
-- Right-click anywhere in the pivot table
-- Select Refresh or Recalculate Pivot Table
-- Or use shortcut: F9 or Shift+F9
-
-#### Solution 2: Check Calculation Settings
-- Go to Tools → Options → LibreOffice Calc → Formula
-- Ensure AutoCalculate is checked
-- Under "Formula options", make sure:
-  - ☑ Automatically find dependencies
-  - ☑ Use OpenCL for formula calculation (if available)
-
-#### Solution 3: Force Complete Recalculation
-- Press Ctrl+Shift+F9 - This forces a complete recalculation of all formulas
-
-#### Solution 4: Check Data Range
-- Right-click the pivot table → Edit Layout
-- Verify the Source data range is correct
-- If you added new rows/columns to your source data:
-  - Edit the data range to include them
-  - Or recreate the pivot table with the new range
-
-#### Solution 5: Pivot Table Corruption
-- If nothing works:
-  - Copy your source data to a new sheet
-  - Create a brand new pivot table
-  - Reconfigure it from scratch
-
-## 💡 Pro Tips for Success
-
-### Tip 1: Naming Your Pivot Tables
-- Right-click the sheet tab
-- Rename it meaningfully:
-  - "Pivot_Subject_Analysis"
-  - "Pivot_Earnings_Summary"
-
-### Tip 2: Formatting for Readability
-- Select the pivot table
-- Use Format → AutoFormat for quick styling
-- Adjust number formats:
-  - Right-click currency values → Format Cells → Currency
-  - Right-click counts → Format Cells → Number
-
-### Tip 3: Saving Your Work
-- Save frequently as .ods (LibreOffice format)
-- If sharing with Excel users, also Save As → .xlsx
-- Consider saving pivot tables as separate files for different analyses
-
-### Tip 4: Documenting Your Process
-- Create a "Notes" sheet in your workbook
-- Document:
-  - What each pivot table shows
-  - Why you chose that configuration
-  - Any insights discovered
-
-## 🔍 Checking Your Work
-
-Compare your results with the example sheets:
-- Pivot table 1A: Basic actor summary
-- Pivot table 1B: Alternative view
-- Pivot table 1C: Different arrangement
-- Pivot table 2A: Subject completion analysis
-- Pivot table 2B: Detailed session analysis
-
-Note: Your teacher may hide the example sheets. If they're hidden, focus on whether your pivot tables provide meaningful insights.
-
-## 🆘 Getting Help
-
-### Common Issues and Solutions:
-| Problem | Solution |
-|--------|---------|
-| "Field not found" error | Check column names match exactly |
-| Numbers showing as text | Use Data → Text to Columns on source data |
-| Pivot table looks empty | Check data range includes all rows/columns |
-| Can't drag fields | Click "More" button in Pivot Table dialog |
-
-### When to Ask for Help:
-- After trying all troubleshooting steps
-- When you get consistent error messages
-- If your results are significantly different from expected
-- When you're spending more than 10 minutes stuck
-
-## 📚 Learning Reflection
-
-After completing all activities, ask yourself:
-- What was the most valuable insight you gained from pivot tables?
-- How much time did pivot tables save compared to manual analysis?
-- What real-world data would you like to analyze with pivot tables?
-- What configuration was most challenging to create?
-
-## ✅ Completion Checklist
-- [ ] Activity 1: Completed manual analysis (10 min challenge)
-- [ ] Activity 2: Created basic pivot table from Data 1
-- [ ] Activity 3: Recreated example pivot tables 1C and 1B
-- [ ] Activity 4: Created pivot tables for Data Set 2 (Challenges A & B)
-- [ ] Verified calculations match examples (or provide meaningful insights)
-- [ ] Saved work in both .ods and .xlsx formats
-- [ ] Documented process and insights in notes
-
-Remember: Pivot tables are a skill that improves with practice. The more you experiment with different configurations, the more powerful insights you'll discover in your data!
