This tool calculates the uncertainty from your data’s standard deviation to help you understand the variability.
Uncertainty from Standard Deviation Calculator
This calculator helps you determine the uncertainty based on the standard deviation and sample size you provide.
How to Use
- Enter the mean (μ) of your data set in the “Mean” field.
- Enter the standard deviation (σ) of your data set in the “Standard Deviation” field.
- Enter the sample size (n) in the “Sample Size” field.
- Click the “Calculate” button to see the results.
How It Calculates
The uncertainty is calculated by dividing the standard deviation (σ) by the square root of the sample size (n). The formula is:
Uncertainty = σ / √n
Limitations
Please note that this calculator is limited by the accuracy of the input data you provide. It assumes that the sample size (n) is greater than 0 and uses a standard normal distribution for calculations.
