Expert Solution

Data is quantitative, if it represents a quantity and in qualitative if it assigns a category to the variable. The data is discrete if it can only take some specific values and in continuous if infinite values are possible in any interval.

Four levels of measurement are nominal, ordinal, interval and ratio. A variable is nominal if it is categorical and cannot be arranged in any order. If ordered arrangement is possible, it is ordinal. If the variable values have meaningful difference between the values, then it is interval and if it has a meaningful 0, it is ratio variable.
