What is the Sampling Error Calculator?

The Sampling Error Calculator is a simple statistical tool designed to determine how much a sample mean differs from the true population mean. By entering the sample mean and population mean, the calculator instantly computes the sampling error, which helps users understand the accuracy and representativeness of their sample data. This tool is especially useful for students, researchers, and analysts working with statistical inference, as it provides a quick way to measure the discrepancy between observed data and the actual population value.

How to Use:

1. Enter Sample Mean (X̄): Input the arithmetic mean calculated from your sample data.
2. Enter Population Mean (μ): Provide the known or expected population mean.
3. Click “Calculate”: The calculator subtracts the population mean from the sample mean to compute the sampling error.
4. Review Result: The output displays the sample mean, population mean, sampling error, and an interpretation explaining the meaning of the result.
