ordinal
Year of birth is interval level of measurement; age is ratio.
The theory behind estimating time of death, or post mortem interval (PMIfor short) with the help of insects is simple: since insects arrive on the body soon after death,estimatingthe age of the insects will also lead to an estimation of PMI.

IQ = mental age / chronological age x 100
he died at age 75.
Ordinal. Though more likely interval or even ratio scale.
Age is none of the items listed. Age is ratio data.

illustrate how you can express the age of group of persons as {1}nominal,{2}ordinal data,{3} interval data,{4}ratio data
Neither, age is at a ratio level of measurement.
Date of birth is considered a ratio variable, not ordinal or interval. While it can indicate order (when someone was born before or after another), it also has a true zero point (the start of the calendar) and allows for meaningful comparisons of differences in age. This distinguishes it from ordinal (which only indicates order) and interval (which lacks a true zero) scales.
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.
No, age is not a nominal variable; it is typically considered a continuous or ordinal variable. Age represents a measurable quantity that can be expressed in years, months, or days, allowing for meaningful mathematical operations. While you can categorize age into groups (like "teenagers," "adults," etc.), the actual age values themselves have a clear order and numerical significance.
Nominal-Genda, religion, post, code, ethnic Ordinal-Satisfaction, exam, grade, position in class Interval-IQ, temperature, score, CGPA Ratio-Height, weight, time, age, grant
Date of birth is not considered nominal data; it is typically classified as ordinal or continuous data. While it consists of categories (days, months, years), it also has a meaningful order and can be used to calculate age. This allows for comparisons and statistical analyses that are not possible with purely nominal data, which lacks a natural ordering.
A person's age is a ratio scale because we can say person A's age is twice older than person B's. Equal difference ages on a ratio scale all have exactly the same size. Moreover in age, 0 (zero) exists, which is feature of a ratio scale.
