ratio
illustrate how you can express the age of group of persons as {1}nominal,{2}ordinal data,{3} interval data,{4}ratio data
Age is none of the items listed. Age is ratio data.
I am not sure if I understand your question. I will rephrase it to: Should data collected on the ages of persons in a group be consider as nominal, ordinal, interval or ratio data? It is ratio. Now, let's try another question. A study finds that people with names beginning with the letter "a-k" are older than people with letters "l-z". In this case, the data collected on names in nominal data, but the ages are still ratio data.
Neither, age is at a ratio level of measurement.
Telephone numbers are actually nominal data.
It is ratio; it has a natural zero and is numerical data.
It is Ordinal:Order the data from smallest to largest or "worst" to "best".Each data value can be compared with another data value.
Nominal Scale < Ordinal< Interval < Ratio
Yes, marital status is nominal data.
No, it is not suitable for nominal data.
If you are bothering to measure it, it probably is not nominal data in your study.
