The most common measures of dispersion for metric variables are the standard deviation and the variance in statistics. These two measures relate each expression of a variable to the mean and indicate how much the individual expressions scatter around the mean. • What is the standard deviation and how do I calculate it? • In statistics, the standard deviation gives you the spread of a variable around its mean. The standard deviation, is the average distance of all measured values of a variable from the mean of the distribution. • The measure of dispersion standard deviation thus indicates how much the individual values scatter around the mean value. If the individual values scatter strongly around the mean, the result is a large standard deviation of the variable. • Sorry, in the example of course a standard deviation of 11.50 comes out and not 12.06!!!! • ► Calculate the standard deviation online • https://datatab.net/statistics-calcul... • ► E-BOOK • https://datatab.net/statistics-book • ► Tutorial standard deviation and descriptive statistics • https://datatab.net/tutorial/dispersi... • ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ • 0:00 Introduction • 0:22 What is the standard deviation? • 2:16 How do I calculate the standard deviation? • 4:09 Why are there two formulas? • 5:59 What is the difference with variance? • 7:17 Calculate the standard deviation online.
