Follow the below mentioned empirical rule tutorial and enhance your skills to become a professional Data Scientist<\/a>.<\/p>\n <\/p>\n <\/p>\n The empirical rule states that for a normal distribution of a continuous random variable, nearly all of the data will fall within three standard deviations of the mean.<\/p>\n <\/p>\n The empirical rule can be broken down into three parts:<\/p>\n <\/p>\n 68% of data falls within the first standard deviation from the mean.<\/p>\n 95% fall within two standard deviations.<\/p>\n 99.7% fall within three standard deviations.<\/p>\n <\/p>\n <\/p>\n <\/p>\n The Empirical rule is often in statistics for Forecasting, especially when obtaining the actual data is difficult or Impossible. The rule can give you a rough estimate of what your data collection might look like if you were able to survey the entire population.<\/p>\n This rule applies generally to a continuous random variable X, following the shape of a normal distribution, or bell-curve, with a mean and a standard deviation.<\/p>\n The rule doesn\u2019t apply to distributions that are not normal<\/p>\n <\/p>\n <\/p>\n When applying the Empirical Rule to a data set the following conditions are true:<\/p>\n Approximately 68%<\/strong> of the data falls within one standard deviation of the mean (or between the mean \u2013 one time the standard deviation, and the mean + 1 times the standard deviation). In mathematical notation, this is represent as \u03bc \u00b1 1\u03c3<\/p>\n pr(\u03bc\u2212\u03c3\u2264x\u2264\u03bc+\u03c3) = 68.27<\/strong><\/p>\n Approximately 95%<\/strong> of the data falls within two standard deviations of the mean (or between the mean \u2013 2 times the standard deviation, and the mean + 2 times the standard deviation). The mathematical notation for this is: \u03bc \u00b1 2\u03c3<\/p>\n pr(\u03bc\u22122\u03c3\u2264x\u2264\u03bc+2\u03c3) = 68.27 %<\/strong><\/p>\n Approximately 7%<\/strong> of the data falls within three standard deviations of the mean (or between the mean \u2013 three times the standard deviation and the mean + three times the standard deviation). The following notation is to represent this fact: \u03bc \u00b1 3\u03c3<\/p>\n pr(\u03bc\u22123\u03c3\u2264x\u2264\u03bc+3\u03c3) = 99.73 %<\/strong><\/p>\n <\/p>\n <\/p>\n In a recent report, during research in a school, it was found that the heights of the students of class 6 were found to be in a normal distribution. If the mean height is 1.5 and the standard deviation by 0.08; then classify the data in accordance with an empirical rule.<\/p>\n <\/p>\n <\/p>\n <\/p>\nWhat is Empirical rule in statistics?<\/h2>\n
