It is a nominal scale.
Nominal (categorical), and Dependent (it is measured and accounted for, but a researcher cannot manipulate gender).
A nominal variable is where you assign a number to a category. Imagine a variable called "animal" where 1=sheep, 2=cow, 3=dog, etc. Calculating the average, standard deviation or other continuous measures of "animal" in this context wouldn't make any sense. That is, an average "animal" of, say, 4.567 with standard deviation of 1.234 doesn't mean anything. You could, however, calculate a mode, which is the most frequently occurring category.
There are a number of situations when it does not make sense. Among these, the two main reasons are:The variable along the x-axis is nominal (categorical) or ordinal.The variable along the y-axis is not continuous.
They are nominal.
It is a nominal scale.
No. It is a discrete quantitative variable.
Nominal and ordinal variables are both qualitative or discrete variables. Nominal variables allow for only qualitative classification while an ordinal variable is a nominal variable, but its different states are ordered in a meaningful sequence.
A nominal variable is a variable measured in current dollars (the value of the dollar for the specific period discussed), and a real variable is a variable measured in constant dollars (the value of the dollar for the base period). That is, a real variable adjusts for the effects of inflation.
They are part of nominal data if the study is about different kinds of methods for displaying statistical data.

No. A discrete variable is one that takes discrete numerical values. But a discrete variable can be ordered while a nominal one cannot. Age, in years, is a discrete variable, and you can say that a 10-year old is younger than a 20-year old who is younger than a 40-year old. Favourite fruit would generate a nominal variable but you cannot say that a banana is more than an apple which, in turn, is more than an orange, etc. (Remember, you are talking only of the nominal values of the fruit - not their price or size or nutritional value or any such characteristic.)
'Nominal' means 'named'. So a 'nominal' voltage is the named voltage of a system. For example, when we talk about a 120-V or 240-V system, we are describing their nominal values, not their actual values which can change from moment to moment.
