<selectRandomNumbers/>
<selectRandomNumbers/> creates named variants from a generates random numbers from a specified range of
values or within a normal distribution around a specified mean.

Example: Default <selectRandomNumbers/>
Without any attributes specified, the default selection type is uniform, and the default interval is . Select a different page variant to view a different selection.
Example: numToSelect
The <selectRandomNumbers/> component is used with the numToSelect attribute to select multiple random values in the default interval . The default type is uniform. The component is nested within an <asList> component for greater clarity when rendering.
Example: assignNames
The assignNames attribute is used to specify unique identifiers for each selection where one more than one selection is required. If only one selection is required, the name of the selection itself assumes the selected value.
Select a different page variant to view a different selection.
Example: from, to
The <selectRandomNumbers/> component is used with the from and the to attributes to modify the default selection interval. The default type is uniform.
Select a different page variant to view a different selection.
Example: type = “discreteUniform”
The type attribute of the <selectRandomNumbers/> component is specified as discreteUniform. The discreteUniform selection generates values from an evenly spaced range defined by the attributes to, from, and step. If left unspecified, the default step is 1.
Select a different page variant to view a different selection.
Example: exclude
The type attribute of the <selectRandomNumbers/> component is specified as discreteUniform. Values can be excluded from the specified range used with this type using the exclude attribute.
Select a different page variant to view a different selection.
Example: step
The type attribute of the <selectRandomNumbers/> component is specified as discreteUniform. The discreteUniform selection generates values from an evenly spaced range defined by the attributes to, from, and step. If left unspecified, the default step is 1.
Select a different page variant to view a different selection.
Example: type = “gaussian”
The type attribute of the <selectRandomNumbers/> component is specified as gaussian. The gaussian selection generates standard normal variables (mean 0, variance 1). Alternatively, the mean as well as the variance or the standardDeviation attributes may be defined.
Select a different page variant to view a different selection.
Example: gaussian with mean and variance
The type attribute of the <selectRandomNumbers/> component is specified as gaussian. The gaussian selection generates standard normal variables (mean 0, variance 1). In this example, the mean and the variance are defined with attributes.
Select a different page variant to view a different selection.
Example: gaussian with mean and standardDeviation
The type attribute of the <selectRandomNumbers/> component is specified as gaussian. The gaussian selection generates standard normal variables (mean 0, variance 1). In this example, the mean and the standardDeviation are defined with attributes.
Select a different page variant to view a different selection.
