NettetThese numerical values (68 - 95 - 99.7) come from the cumulative distribution function (CDF) of the normal distribution. For example, F (2) = 0.9772, or Pr (x ≤ μ + 2σ) = 0.9772. Note that this is not a symmetrical interval – this is merely the probability that an observation is less than μ + 2σ. elaine quijano bodyNettetMound shape is the shape which is created when data points are being used for plotting a line pertaining to a specific item that complies with the criteria of the normal … elaine odomNettet5. mar. 2024 · Empirical Rule: The empirical rule is the statistical rule stating that for a normal distribution , almost all data will fall within three standard deviations of the mean.
