Difference Between Ordinal Data and Interval Data

Ordinal data are most concerned about the order and ranking while interval data are concerned about the differences of value within two consecutive values. ... Ordinal data place an emphasis on the position on a scale while interval data are on the value differences of two values in a scale.

What is the difference between categorical ordinal and interval variables?

An ordinal variable is similar to a categorical variable. The difference between the two is that there is a clear ordering of the categories. ... If these categories were equally spaced, then the variable would be an interval variable.

What is an example of interval data?

Interval data is measured on an interval scale. A simple example of interval data: The difference between 100 degrees Fahrenheit and 90 degrees Fahrenheit is the same as 60 degrees Fahrenheit and 70 degrees Fahrenheit. ... For example, Object A is twice as large as Object B is not a possibility in interval data.

What is the difference between nominal ordinal interval and ratio data?

In summary, nominal variables are used to “name,” or label a series of values. Ordinal scales provide good information about the order of choices, such as in a customer satisfaction survey. Interval scales give us the order of values + the ability to quantify the difference between each one.

Is age nominal or ordinal?

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 grade level an ordinal variable?

Ordinal (ordered) variables, e.g., grade levels, income levels, school grades. Discrete interval variables with only a few values, e.g., number of times married. Continuous variables grouped into small number of categories, e.g., income grouped into subsets, blood pressure levels (normal, high-normal etc)

Is age an example of interval data?

Interval-level variables are continuous, meaning that each value of the variable is one increment larger than the previous and one smaller than the next value. Age, if measured in years, is a good example; each increment is one year.

What are intervals in data?

Interval data is measured along a numerical scale that has equal distances between adjacent values. These distances are called “intervals.” There is no true zero on an interval scale, which is what distinguishes it from a ratio scale.

Is ordinal data qualitative or quantitative?

Data at the ordinal level of measurement are quantitative or qualitative. They can be arranged in order (ranked), but differences between entries are not meaningful. Data at the interval level of measurement are quantitative. They can be ordered, and meaningful differences between data entries can be calculated.

What is an example of ordinal measurement?

Examples of ordinal variables include: socio economic status (“low income”,”middle income”,”high income”), education level (“high school”,”BS”,”MS”,”PhD”), income level (“less than 50K”, “50K-100K”, “over 100K”), satisfaction rating (“extremely dislike”, “dislike”, “neutral”, “like”, “extremely like”).

Is weight nominal or ordinal?

4. Nominal Ordinal Interval Ratio. Weight is measured on the ratio scale.

How do you know if data is nominal or ordinal?

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.
