Statistics for Business Analytics Using MS Excel — Lesson 2: Probability, Sampling, and Statistical Distributions

Learning Objectives

• Apply probability rules, conditional probability, expected value, and risk concepts
• Compare common distributions and select suitable assumptions for business scenarios
• Use sampling methods, confidence intervals, and estimation techniques in Excel

Detailed Topics

• Apply probability rules: Apply probability rules, conditional probability, expected value, and risk concepts
• Compare common distributions and select suitable assumptions for business scenarios: Compare common distributions and select suitable assumptions for business scenarios
• Use sampling methods: Use sampling methods, confidence intervals, and estimation techniques in Excel

Guided Demonstration

1. Review the requirement, environment, dependencies, roles, risks, and expected outcome.
2. Demonstrate the relevant configuration, analysis, code, or administration workflow step by step.
3. Capture settings, outputs, logs, screenshots, calculations, or test evidence.
4. Compare the observed result with the stated acceptance criteria.

Hands-On Activity

Estimate a business metric from sample data and document assumptions and confidence.

• Document assumptions and the planned sequence before making changes.
• Complete the activity and preserve evidence of normal and exception behavior.
• Record issues, corrective actions, and reusable operational or development notes.

Troubleshooting Focus

• Separate symptoms from causes and collect evidence before applying a fix.
• Check configuration, permissions, data, dependencies, capacity, connectivity, and recent changes.
• Validate rollback, recovery, support ownership, and user or business impact.

Validation Checklist

• The requirement and expected outcome are clear.
• The selected configuration, design, query, code, or process is documented.
• Normal, boundary, failure, security, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply Probability, Sampling, and Statistical Distributions in a realistic scenario and validate the result with documented evidence.
