Mean
A nominal variable is a type of categorical variable that represents distinct categories without any inherent order or ranking. Examples include gender, nationality, or favorite color, where the values serve to label different groups. Since nominal variables do not have a quantitative value, statistical analysis typically involves counting occurrences or determining proportions within each category.
It is a nominal scale.
Yes, race is considered a categorical variable because it represents distinct groups or categories based on shared physical, cultural, or social characteristics. Categorical variables can be nominal, where there is no inherent order (e.g., different racial groups), or ordinal, where categories have a meaningful order. In statistical analysis, race is often used to categorize individuals for various studies and comparisons.
Nominal (categorical), and Dependent (it is measured and accounted for, but a researcher cannot manipulate gender).
For a nominal variable like religious affiliation, a representative value is typically the mode, which is the category that occurs most frequently in the dataset. Since nominal variables do not have a natural order or numerical value, the mode provides insight into the most common group within the data. Other descriptive statistics, such as percentages or proportions, can also be useful for summarizing the distribution of various affiliations.

No. It is a discrete quantitative variable.
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.

'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.
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.)
Three basic levels of measurement are nominal, ordinal, and interval/interval-ratio.
