Square Roots in Normal Distributions
- The normal distributionalso uses a square root, although it is not easy to see from the graph (which has the shape of a symmetric bell curve). The square root in a normal distribution can be seen in its pdf (probability density function), which is given by: Without square roots, we could not define the function that gives us a normal distribution curve. This distribution is used throughou…
