Natural Resource BiometricsDistributionsDistributions generally describe the shape by a name. this are both the shape of the generating distribution. There are several common distributions" Normal, Student's t, F, Z, χ^{2}. Distributions have 4 basic moments that describe the distribution.
Normal Distributions are the most commonly used distribution in statistics. It is a symmetrical bell shaped distribution Figure 1. A normal distribution with mean = 100, and standard deviation 15. The mean is the vertical line. Figure 2. A normal distribution with mean = 100, and standard deviation 15. One standard deviation is shown in red. Figure 3. A normal distribution with mean = 100, and standard deviation 15. Two standard deviations are shown in red. Figure 4. A normal distribution with mean = 100, and standard deviation 15. Three standard deviations are shown in red.
