  • Bell Shaped Curve: Normal Distribution In Statistics
    If the data values in a normal distribution are converted to standard score (z-score) in a standard normal distribution, the empirical rule describes the percentage of the data that fall within specific numbers of standard deviations (σ) from the mean (μ) for bell-shaped curves
  • 68–95–99. 7 rule - Wikipedia
    In statistics, the 68–95–99 7 rule, also known as the empirical rule or 68–95–99 7 rule for a normal distribution[1] and sometimes abbreviated 3sr or 3 σ, is a shorthand used to remember the percentage of values that lie within an interval estimate in a normal distribution: approximately 68%, 95%, and 99 7% of the values lie within one
