Statistical Formulas
Mean (Average)
μ = (x₁ + x₂ + ... + xₙ) / n
Sum of all values divided by count
Standard Deviation
σ = √[Σ(x - μ)² / n]
Square root of variance
Variance
σ² = Σ(x - μ)² / n
Average of squared differences from mean
Median
Middle value when sorted
For even count: average of two middle values
Mode
Most frequently occurring value(s)
Can have multiple modes
Range
Range = Maximum - Minimum
Difference between highest and lowest values

Practice Problems
Problem 1:
Find mean of: 2, 4, 6, 8, 10
Solution: (2+4+6+8+10)/5 = 30/5 = 6
Problem 2:
Find median of: 1, 3, 5, 7, 9
Solution: Middle value = 5
Problem 3:
Find range of: 10, 15, 20, 25, 30
Solution: 30 - 10 = 20
Problem 4:
Find mode of: 2, 3, 3, 4, 5
Solution: Mode = 3 (appears twice)
Problem 5:
Calculate variance of: 1, 2, 3
Solution: Mean=2, Variance=[(1-2)²+(2-2)²+(3-2)²]/3=0.67
