Nominal level Hair color is an example of a nominal level of measurement. Nominal measures are categorical, and those categories cannot be mathematically ranked. There is no ranking order between hair colors.
What type of data is hair color?
Hair color, blood type, ethnic group, the car a person drives, and the street a person lives on are examples of qualitative data. Qualitative data are generally described by words or letters. For instance, hair color might be black, dark brown, light brown, blonde, gray, or red.
What type of variable is color?
Categorical variables Categorical variables (or nominal variables)—such as race, gender, place of birth, color, type of medication, or the names of medical disorders—are objects you can count but that are more interesting because of the categories into which they fall.
Is hair color dichotomous variable?
Variables can broadly be divided into two types, categorical and numerical. Categorical variables can be dichotomous (also called binary), nominal or ordinal. Nominal variables (from Latin for name) are things like eye colour or hair colour. We might have: 1=blue eyes, 2=brown eyes, 3=green eyes.
Is hair color a ordinal variable?
An example of a nominal-level variable is hair colour: people could be assigned to blonde, red, brown, etc., but there is no way to rank colours from low to high. When the categories CAN be ranked, it is considered an ordinal variable.
What type of data is color of hair?
Hair colour is a type of discrete data because the values are distinct. You either have one hair colour or another! Continuous data covers a range, so each category is not separate but runs into the next. We represent this data in a histogram.

Frequently Asked Questions
What are the 4 levels of measurement in statistics?
Statisticians often refer to the "levels of measurement" of a variable, a measure, or a scale to distinguish between measured variables that have different properties. There are four basic levels: nominal, ordinal, interval, and ratio.
What are the 5 basic statistics?
5 basic statistics concepts
- Regression. Regression is a method for comparing two variables when one of them is independent and the other, or the others, depends on that first variable.
- Calculating the mean.
- Standard deviation.
- Sample size determination.
- Hypothesis testing.
Is hair color an example of a quantitative variable?
Qualitative variables are those that express a qualitative attribute such as hair color, eye color, religion, favorite movie, gender, and so on. The values of a qualitative variable do not imply a numerical ordering.
- Is hair color a continuous variable?
- Hair colour is a type of discrete data because the values are distinct. You either have one hair colour or another! Continuous data covers a range, so each category is not separate but runs into the next.
- Why the variable male is categorical?
- Male is categorical because it has two categories, 1 representing males and 0 representing females.
- Is the variable number of siblings numerical or categorical explain?
- The number of siblings and student height represent numerical variables. Because the number of siblings is a count, it is discrete. Height varies continuously, so it is a continuous numerical variable.
What type of variable is hair color
|Can a categorical qualitative variable have values that are numeric Why or why not?
|No: by definition, qualitative variables must be categories or nonnumeric data. B. No: numeric variables have values that can be added or subtracted in a meaningful way, making them quantitative rather than qualitative.
|Which variables are categorical?
|A categorical variable is a variable with a set number of groups (gender, colors of the rainbow, brands of cereal), while a numeric variable is generally something that can be measured (height, weight, miles per hour).
|What type of variable is the color of hair?
|Hair color is also a categorical variable having a number of categories (blonde, brown, brunette, red, etc.) and again, there is no agreed way to order these from highest to lowest. A purely nominal variable is one that simply allows you to assign categories but you cannot clearly order the categories.

- Is color of hair dye quantitative or qualitative?
- Yes, color is considered a qualitative variable in statistics. Qualitative variables, also known as categorical variables, represent categories or groups that have no inherent order or numerical value.
- Is hair color nominal or ordinal?
- Nominal- An example of a nominal-level variable is hair colour: people could be assigned to blonde, red, brown, etc., but there is no way to rank colours from low to high. When the categories CAN be ranked, it is considered an ordinal variable.
