How to Calculate Standard Error?
Various steps to calculate the standard error are added below,
Step 1: Find the number of measurement(n) and find the sample mean(μ).
Step 2: Find the variation of sample values from the mean value.
Step 3: Find the square of the deviation and find their sum. Σ(xi – μ)²
Step 4: Divide the sum from step 3 by (n-1).
Step 5: Take the square root of the number, i.e. standard deviation (σ).
Step 6: Divide the standard deviation by the square root of measurement(n).

Standard Error
Standard Error is the measure of the variability of a sample statistic used to estimate the variability of a population. Standard Error is important in dealing with sample statistics, such as sample mean, sample proportion, etc. Sample Error Formula is used to determine the accuracy of a sample that reflects a population. The standard error formula is the discrepancy between the sample mean and the population mean.
In this article, we will learn about, Standard Error, Standard Error Formula, Standard Error of Mean, Standard Error of Estimate, related Examples, and Error in detail.
