Can more types of calculations be performed at a nominal level than an interval level?
No. The interval level is more refined and so enables calculations which are not available at the nominal level.
Differences between ordinal scale and nominal scale?
I've included a couple of links which should explain better the differences among the four levels of measurement: Nominal, Ordinal, Interval and Ratio. The nominal level can be thought of as the "name" level. I'll give you an example of nominal level of measurement. Perhaps you are collecting data on the types of cars that go through an intersection. You classify the vehicles passing by as trucks, cars and motorcycles and count how many of each pass by. Ordinal is the "order" level, where some natural order of data is possible. The difference between measurements has no physical meaning. An example of ordinal level of measurement. A hospital asks in the emergency room, for patients to describe their pain on a level of 1 to 10, which 10 being the most severe. As given in the first link, it is interesting that there is not complete agreement on this system of classification.
Is the category of ages nominal or ordinal data?
Neither, age is at a ratio level of measurement.
What level of measurement is school grade level?
· Dependent variable ( student's academic achievement ) : It depend on the way that we use it to write the score (if we write it as a letter it will be an ordinal ,but if we write it as number it will be an interval). · Independent variable ( intelligent ) : Interval, · Independent variable ( attention ) : Interval,
What level of measurement is required to determine the mode?
nominal
What is the level of measurement for Year of Birth nominal or ordinal?
Year of birth is interval level of measurement; age is ratio.
What level of measurement is the amount of gasoline pumped by a filling station during a day nominal ordinal interval ratio?
It is ratio; it has a natural zero and is numerical data.
What scale of measurement is educational level?
nominal
Can more types of calculations be performed at a nominal level than an interval level?
No. The interval level is more refined and so enables calculations which are not available at the nominal level.
Is Gender nominal or ordinal?
Gender is nominal. Nominal is categorical only; no ordering scheme. Ordinal level of measurement places some order on the data, but the differences between the data can't be determined or are meaningless.

What are Levels of measurement in statistics?
Nominal, ordinal, interval and ratio (NOIR) are four levels of measurement typically recognized in the statistical literature. At the nominal level, objects are categorized with names, identifiers or labels such as colors like red, yellow and blue. TAnother example is the answers on a survey sheet, Yes, No, and Undecided. At the ordinal level, the data can be ordered. Course grades A,B, C, D and E is an example. At the interval level, the data can be ordered and the difference between data values has meaning. Temperature in degrees F is an example. At the ratio level, there is a natural zero starting point and differences and ratios have meaning.
IS A major limitation of the nominal level of measurement is that a particular score represents only position with respect to some other score?
no. its a limitation of an ordinal variable not a nominal.
What level of measurement is grade level?
· Dependent variable ( student's academic achievement ) : It depend on the way that we use it to write the score (if we write it as a letter it will be an ordinal ,but if we write it as number it will be an interval). · Independent variable ( intelligent ) : Interval, · Independent variable ( attention ) : Interval,

What levels of measurement are most variables in behavioral and social science research?
Variables in behavioral and social science research are often measured at the interval or ratio level. This allows for more meaningful statistical analysis and interpretation of data. However, some variables may also be measured at the ordinal or nominal level depending on the research question and study design.
