Mathematical Formula & Variables
Equation Model
SE = s / sqrt(n)Standard Error formula dividing sample standard deviation by square root of sample size.
Variable Definitions
| Symbol | Description |
|---|---|
| s | Sample standard deviation |
| n | Total sample size count |
How to Use the Standard Error Calculator
- Enter sample data values separated by commas.
- Or enter pre-calculated sample standard deviation (s) and sample size (n).
- Calculate Standard Error (SE), mean, and 95% confidence bounds.
Practical Example Calculation
Scenario Context: Sample dataset [10, 12, 15, 18, 20] with n = 5.
Step 1: Mean = 15.0.
Step 2: Sample Standard Deviation s = 4.062.
Step 3: SE = 4.062 / sqrt(5) = 4.062 / 2.236 = 1.817.
Mean = 15.0 | Standard Error (SE) = 1.817.
