Celebrating questions gives confidence to the students who ask them. Since it is structured, it can be easily arranged and understood. For example, the exact amount of gas purchased at the pump for cars with 20-gallon tanks would be continuous data from 0 gallons to 20 gallons, represented by the interval [0, 20], inclusive. You can certainly convert labeled data to 'numbered' data. I know that to make a normal correlation matrix I should only have normalised numeric variables, but this is not the case. Thanks. 1. position along a common scale. Discrete data can usually be counted in a finite matter. When a car breaks down on the highway, the emergency dispatcher may ask for the nearest mile marker. For categorial data it should be differentiated between nominal and ordinal data, where ordinal data exhibits . To learn more, see our tips on writing great answers.

(representing the countably infinite case). \r\n \t
- Continuous data represent measurements; their possible values cannot be counted and can only be described using intervals on the real number line. The list of possible values may be fixed (also called finite); or it may go from 0, 1, 2, on to infinity (making it countably infinite).For example, the number of heads in 100 coin flips takes on values from 0 through 100 (finite case), but the number of flips needed to get 100 heads takes on values from 100 (the fastest scenario) on up to infinity (if you never get to that 100th heads). histogram. Most of the time, these data are collected as part of the subject being looked at.
