What is sequential data?
A form of ordered data, where the value can range from minimum to maximum.
What is diverging data?
A form of ordered data, where the value can be deconstructed into two sequences pointing in opposite directions that meet a common zero point.
What is cyclic data (attribute)?
Values that wrap around back to a starting point as opposed to increasing indefinitely.
What a hierarchical attributes?
