Is ethnicity nominal or ordinal?

Categorical variables can be sub-classified as nominal or ordinal with ordinal variables have a natural ordering, whereas nominal variables do not.

Gender, Diabetes and Race/Ethnicity were nominal categorical variables, they have no natural order and individuals can only be put into categories for these variables..

Is salary nominal or ordinal?

In this case, salary is not a Nominal variable; it is a ratio level variable. The appropriate test of association between undergraduate major and salary would be a one-way Analysis of Variance (ANOVA), to see if the mean starting salary is related to undergraduate major.

What is a true zero point?

Identity means that each number has a particular meaning. Magnitude means that numbers have an inherent order from smaller to larger. … Absolute/true zero means that the zero point represents the absence of the property being measured (e.g., no money, no behavior, none correct).

Can I use mean for ordinal data?

However, strictly speaking, ordinal data has a median and mode only, and nominal data has only a mode. However, a consensus has not been reached among statisticians about whether the mean can be used with ordinal data, and you can often see a mean reported for Likert data in research.

What is an ordinal categorical variable?

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.

Is age ordinal or nominal?

Age can be both nominal and ordinal data depending on the question types. I.e “How old are you” is a used to collect nominal data while “Are you the first born or What position are you in your family” is used to collect ordinal data. Age becomes ordinal data when there’s some sort of order to it.

Is gender ordinal or nominal?

Which data types has true zero?

Ratio data tells us about the order of variables, the differences between them, and they have that absolute zero.

What type of data is ordinal data?

Ordinal data is a categorical, statistical data type where the variables have natural, ordered categories and the distances between the categories is not known. These data exist on an ordinal scale, one of four levels of measurement described by S. S.

What data type is age?

For example, age and weight would be considered numerical variables, while phone number and ZIP code would not be considered numerical variables. There are 2 types of numerical variables: ● Continuous variable: A numerical variable that can take values on a continuous scale (e.g. age, weight).

What is difference between nominal and ordinal data?

Nominal and ordinal are two of the four levels of measurement. Nominal level data can only be classified, while ordinal level data can be classified and ordered.

Is age nominal or ordinal in SPSS?

Age is frequently collected as ratio data, but can also be collected as ordinal data. This happens on surveys when they ask, “What age group do you fall in?” There, you wouldn’t have data on your respondent’s individual ages – you’d only know how many were between 18-24, 25-34, etc.

Is blood pressure nominal or ordinal?

Most physical measures, such as height, weight, systolic blood pressure, distance etc., are interval or ratio scales, so they fall into the general “continuous ” category. Therefore, normal theory type statistics are also used when a such a measure serves as the dependent variable in an analysis.

Can ordinal data be continuous?

In some cases, the measurement scale for data is ordinal, but the variable is treated as continuous. For example, a Likert scale that contains five values – strongly agree, agree, neither agree nor disagree, disagree, and strongly disagree – is ordinal.
