Error

Standard error is a fundamental concept in statistics that plays a pivotal role in determining the reliability and precision of estimates derived from sample data. It is a measure of the variability or dispersion of sample statistics, such as the sample mean when compared to the population parameter. In this article, we will explore what standard error is, how it is calculated, and why it is essential in statistical analysis. What is Standard Error? Standard error often denoted as SE or SE (), is a statistical measure used to quantify the variation or uncertainty associated with an [...]
