Standard Error of the Mean, Concept and Formula: What is the standard error of the sample mean in statistics and what does it show? Why does Standard Error formula equal to Standard deviation Over Square Root of n?

In this statistics video tutorial we will learn why the Standard deviation of the Mean (or the Standard Error of The Mean) is equal to the standard deviation divided by the square root of the sample size. While the formula for Standard Deviation of mean is presented as ''sigma over root n'', this often appears as a 'magical' result! here, we spend a few minutes deriving the formula and explore where it is coming from. We do this in a separate video so that we can provide justification for why this is the formula, while not letting that derivation become a distraction when presenting topics that make use of the standard deviation of the mean. ►► Watch More: ► Intro to Statistics Course (Complete Series): https://bit.ly/2SQOxDH ►Data Science with R (Complete Series): https://bit.ly/1A1Pixc ►Getting Started with R (Series 1): https://bit.ly/2PkTneg ►Graphs and Descriptive Statistics in R (Series 2): https://bit.ly/2PkTneg ►Probability distributions in R (Series 3): https://bit.ly/2AT3wpI ►Bivariate analysis in R (Series 4): https://bit.ly/2SXvcRi ►Linear Regression in R (Series 5): https://bit.ly/1iytAtm ►ANOVA Concept and with R https://bit.ly/2zBwjgL ►Hypothesis Testing: https://bit.ly/2Ff3J9e ►Linear Regression Concept and with R Lectures https://bit.ly/2z8fXg1 Follow MarinStatsLectures Subscribe: https://goo.gl/4vDQzT website: https://statslectures.com Facebook: https://goo.gl/qYQavS Twitter: https://goo.gl/393AQG Instagram: https://goo.gl/fdPiDn Our Team: Content Creator: Mike Marin (B.Sc., MSc.)
