A split- face CMU is made by treating a standard CMU with an oxyacetylene torch to produce a very smooth surface on one or more faces of the unit.
Empirical Rule
The empirical rule, also known as the 68-95-99.7 rule, states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% within two, and 99.7% within three.
Normal Curve
A symmetrical, bell-shaped curve that represents the distribution of values, deviations, or probabilities for a set of data in which most measurements cluster around the mean.
Bell-Shaped
A bell-shaped curve is a graph of a distribution that resembles the shape of a bell, typically representing a normal distribution in which the bulk of the values lie towards the center and taper off symmetrically towards the extremes.
Standard Deviation
A measure of the dispersion or variability within a set of numerical data, indicating how spread out the values are.
