📊 About Mean (Average)
• Formula: Mean = Sum of all values ÷ Number of values
• Use case: Find the typical or central value in a dataset
• When to use: Data without extreme outliers
• Example: Average test scores, average income, average temperature
• Tip: Mean is sensitive to outliers - consider median for skewed data
