This tool helps you easily calculate and correct errors on your webpage.
How to Use the Error Calculator
Follow the steps below to use the error calculator:
- Enter the mean value in the “Mean” field.
- Enter the standard deviation value in the “Standard Deviation” field.
- Enter the sample size in the “Sample Size” field.
- Click the “Calculate” button to compute the results.
How It Calculates the Results
The calculator takes the mean, standard deviation, and sample size as inputs. It then calculates:
- Standard Error: Standard deviation divided by the square root of the sample size.
- 95% Confidence Interval Lower Bound: Mean minus 1.96 times the standard error.
- 95% Confidence Interval Upper Bound: Mean plus 1.96 times the standard error.
Limitations
Please note that this calculator makes certain assumptions:
- The sample follows a normal distribution.
- The input values are strictly greater than zero.
Incorrect inputs such as negative values, zero, or non-numeric entries will result in an error message. Ensure that input values are correct before proceeding.
