Sample Standard Deviation (s, N - 1)
5,2372
Used when analyzing a sample from a larger population.
Population Standard Deviation (σ, N)
4,899
Used when analyzing the entire dataset/population.
Mean (x̄)
18
Sample Variance (s²)
27,4286
Population Variance (σ²)
24
Sum of Squares (SS)
192
Step-by-Step Variance and Deviation
1. Calculate Mean (μ or x̄): Σx / N = 144 / 8 = 18
2. Calculate Deviations from Mean (x - x̄) and square each result
3. Sum of Squared Deviations (SS): Σ(x - x̄)² = 192
4. Population Variance (σ²): SS / N = 192 / 8 = 24
5. Population Standard Deviation (σ): √(σ²) = √(24) = 4.899
6. Sample Variance (s²): SS / (n - 1) = 192 / (8 - 1) = 27.4286
7. Sample Standard Deviation (s): √(s²) = √(27.4286) = 5.2372

Step-by-Step Examples

Analisis 8 Data Angka

Data: 10, 12, 23, 23, 16, 23, 21, 16

Inputs: Data: 10, 12, 23, 23, 16, 23, 21, 16
Result: Sampel s = 5.2372, Populasi σ = 4.8989

Rata-rata = 18.00. Jumlah kuadrat deviasi SS = 192.00.
