LibreOffice Calc: Analysis Tools
1. Goal Seek
Definition: Goal Seek helps find an unknown input when the output is predefined.
Example:
Find the interest rate required for a loan where the EMI is ₹5,000.
Steps:
1. Enter loan details (Principal ₹1,00,000, Interest Rate, EMI ₹5,000).
2. Go to Tools > Goal Seek.
3. Set "Target Cell" as EMI (₹5,000).
4. Set "Variable Cell" as Interest Rate.
5. Click OK to compute the interest rate.
1. Enter loan details (Principal ₹1,00,000, Interest Rate, EMI ₹5,000).
2. Go to Tools > Goal Seek.
3. Set "Target Cell" as EMI (₹5,000).
4. Set "Variable Cell" as Interest Rate.
5. Click OK to compute the interest rate.
2. Scenario Manager
Definition: Used for "What-If" analysis to compare different data conditions.
Example:
Comparing best-case, average-case, and worst-case sales scenarios.
Steps:
1. Enter sales data for different scenarios.
2. Go to Tools > Scenarios.
3. Add different values and name them (Best, Average, Worst).
4. Click OK and switch between scenarios.
1. Enter sales data for different scenarios.
2. Go to Tools > Scenarios.
3. Add different values and name them (Best, Average, Worst).
4. Click OK and switch between scenarios.
3. Data Consolidation
Definition: Merges and summarizes data from multiple sources.
Example:
Combining sales data from multiple branches.
Steps:
1. Open multiple sheets with sales data.
2. Go to Data > Consolidate.
3. Select source data ranges.
4. Choose SUM to get total sales.
5. Click OK, and data will be merged.
1. Open multiple sheets with sales data.
2. Go to Data > Consolidate.
3. Select source data ranges.
4. Choose SUM to get total sales.
5. Click OK, and data will be merged.
4. Solver
Definition: Solver finds the best possible solution by adjusting variables under constraints.
Example:
Maximizing profit for a factory with limited resources.
Steps:
1. Enter profit per unit for chairs & tables.
2. Define constraints (budget, labor, materials).
3. Go to Tools > Solver.
4. Set "Target Cell" as profit (maximize).
5. Click Solve to compute the best combination.
1. Enter profit per unit for chairs & tables.
2. Define constraints (budget, labor, materials).
3. Go to Tools > Solver.
4. Set "Target Cell" as profit (maximize).
5. Click Solve to compute the best combination.
Summary of Key Uses:
- Goal Seek: Find unknown inputs for a given output (e.g., EMI calculation).
- Scenario Manager: Compare different data conditions (e.g., best/worst sales cases).
- Data Consolidation: Merge multiple datasets (e.g., sales from different branches).
- Solver: Optimize decision-making (e.g., maximize profit under constraints).
