Step 2: The diameter of 120 cm is one standard deviation below the mean. Shade below that point. Step 3: Add the percentages in the shaded area: 0.15 % + 2.35 % + 13.5 % = 16 %. For example, if the mean of a normal distribution is five and the standard deviation is two, the value 11 is three standard deviations above (or to the right of) the mean. The calculation is as follows: x = μ + (z)(σ) = 5 + (3)(2) = 11. The z-score is three. The mean for the standard normal distribution is zero, and the standard deviation is one. Between 2021 and 2022: Real median household income fell by 2.3 percent. Income inequality, as measured by the Gini index, decreased by 1.2 percent.

The standard normal distribution is a normal distribution of standardized values called z-scores. A z-score is measured in units of the standard deviation. For example, if the mean of a normal distribution is five and the standard deviation is two, the value 11 is three standard deviations above (or to the right of) the mean. The Percentile Chart, or Cumulative Distribution Function (CDF), is commonly used as a way to visualize the distribution of values in a dataset. Often times just looking at just the average or min/max of the data might be misleading and understanding the distribution of the data is as important as the aggregated value itself..
