Enter a list of numbers to calculate standard deviation and variance instantly.
The calculator computes variance and standard deviation using the population formulas:
Mean = (Σx) / n Variance = Σ(x − mean)² / n Standard Deviation = √Variance
Standard deviation measures how spread out the numbers are from the mean.
Input: 5, 8, 2, 8, 3, 9 Possible Output: Mean = 5.83 Variance = 7.47 Standard Deviation = 2.73
