Let X is a normal variate with mean µ and standard deviation σ. Then Z=(X-µ)/σ is a Standard Normal Variate.Hence the Standard Normal Variate can be used to find the probability regarding X.The expected value of a standard normal variable X is E[X]=0 and th...
Standard normal random variable, a special (unique) form of a normal random variable, can be used to find the probabilities (cumulative) related to an arbitrary normal distribution. Therefore, a standard normal table that includes all such...
The normal distribution is a bell-shaped curve where data clusters symmetrically around the mean, useful in statistics and natural phenomena modeling.
A standard normal distribution, Z is defined as {eq}Z = \dfrac{{X - \mu }}{\sigma } {/eq}. The mean of a standard normal variable Z is 0. The... Learn more about this topic: Normal Distribution | Curve, Table & Examples ...
The first step that we must undertake to check if the distribution of the variable follows the normal distribution is to conduct normality testing, which can usually be performed using some of the standard tests that are part of most statistical programs and applications, such as the ...
When a and b are set to "wtf!" in the same line, the Python interpreter creates a new object, then references the second variable at the same time. If you do it on separate lines, it doesn't "know" that there's already "wtf!" as an object (because "wtf!" is not implicitly ...
A nominal scale describes a variable with categories that do not have a natural order or ranking. You can code nominal variables with numbers if you want, but the order is arbitrary and any calculations, such as computing a mean, median, or standard deviation, would be meaningless. ...
Docker is an open source project that's used to create, run and deploy applications in containers. A Docker image contains application code, libraries, tools, dependencies and other files needed to make an application run. When a user runs an image, it can become one or many instances of ...

Simply stated, a SAN is a network of disks that is accessed by a network of servers. There are several popular uses for SANs in enterprise computing. A SAN is typically employed to consolidate storage. For example, it's common for a computer system, such as a server, to include one or...
