What is the difference between nominal and ordinal variables?
Nominal scale is a naming scale, where variables are simply “named” or labeled, with no specific order. Ordinal scale has all its variables in a specific order, beyond just naming them. Interval scale offers labels, order, as well as, a specific interval between each of its variable options.
What are the different types of variables in research?
Parts of the experiment: Independent vs dependent variables
|Type of variable||Definition|
|Independent variables (aka treatment variables)||Variables you manipulate in order to affect the outcome of an experiment.|
|Dependent variables (aka response variables)||Variables that represent the outcome of the experiment.|

discrete (categorical) variables can be further classified into: ➢ nominal variable: no natural ordering between categories (e.g., religious affiliation, mode of transportation, favorite type of music, …) (e.g., size of automobile, social class, political philosophy, patient condition, …)
What is an example of a qualitative variable?
A qualitative variable, also called a categorical variable, is a variable that isn’t numerical. It describes data that fits into categories. For example: Eye colors (variables include: blue, green, brown, hazel).
What is an example of a subject variable?
an experience or characteristic of a research participant that is not of primary interest but nonetheless may influence study results and thus must be accounted for during experimentation or data analysis. Examples include age, marital status, religious affiliation, and intelligence.
Is income a nominal variable?
For example, gender and ethnicity are always nominal level data because they cannot be ranked. However, for other variables, you can choose the level of measurement. For example, income is a variable that can be recorded on an ordinal or a ratio scale: At a ratio level, you would record exact numbers for income.
What type of variable is relationship status?
Categorical Variable. Usually an independent or predictor variable that contains values indicating membership in one of several possible categories. E.g., gender (male or female), marital status (married, single, divorced, widowed).
What is variable and its types?

What are ordinal variables in statistics?
An ordinal variable is a categorical variable for which the possible values are ordered. Ordinal variables can be considered “in between” categorical and quantitative variables.
How do you classify a variable in statistics?
Variables can be classified as qualitative (aka, categorical) or quantitative (aka, numeric).

- Quantitative. Quantitative variables are numeric.

What is Nominal example?
Examples of nominal data include country, gender, race, hair color etc. of a group of people, while that of ordinal data include having a position in class as “First” or “Second”. Note that the nominal data examples are nouns, with no order to them while ordinal data examples comes with a level of order.
What are examples of nominal variables?
You can code nominal variables with numbers if you want, but the order is arbitrary and any calculations, such as computing a mean, median, or standard deviation, would be meaningless. Examples of nominal variables include: genotype, blood type, zip code, gender, race, eye color, political party.

Birth order (ordinal position) in the nuclear family has been found to be related to a large number of social and psychological factors.
Is gender a qualitative variable?
Despite the numerical classification, the variable gender is still a qualitative variable and not a discrete variable as it may look. The numerical classification is only used to facilitate data collection and data management.
Is gender a nominal variable?
For example, gender is a nominal variable having two categories (male and female) and there is no intrinsic ordering to the categories.
In which types of variable can you store text?
Text Variables – This type of variables is used to store the text values. True/False Variables – This type of variables is used to store Boolean values. Number Variables – This type of variables is used to store Integer values. Array Variables – This type of variables is used to store an array of integers or string.
How do we classify variables?
Classifying variables can be somewhat contentious. Standard statistical textbooks will state that variables can be broadly classified as categorical or continuous. Categorical variables can be further categorised into nominal (e.g. ethnic group), ordinal (e.g. tumour staging) and dichotomous (e.g. sex).
