When it comes to data, there are two main types: ordinal and interval. Ordinal data is a set of numbers that can be put in order, such as ranking athletes from first to last. Interval data is a set of numbers that has a specific mathematical value assigned to it, such as the temperature in degrees Fahrenheit. In this post, we’ll explore the differences between these two types of data and how they’re used in research. Stay tuned!

## What is Ordinal Data?

Ordinal data is a type of data that is used to indicate the order or rank of something. For example, if you were to ask people to rate their favourite type of food on a scale from 1-5, the resulting data would be ordinal. Ordinal data is often used in surveys and polls, as it allows for a more granular understanding of people’s preferences and opinions. While ordinal data can be helpful, it is important to keep in mind that it does not provide as much information as other types of data, such as interval or ratio data. As a result, Ordinal data should be interpreted with caution and used in conjunction with other types of data.

## What is Interval Data?

Interval data is a type of data that is measured on a scale. Interval data can be ordinal, meaning that it can be ordered from least to greatest. However, Interval data cannot be ranked. Interval data is often used in scientific studies. For example, when scientists are studying the effects of a new medication, they will use Interval data to track the patients’ blood pressure levels. Interval data is also used in weather studies. Scientists use Interval data to track changes in temperature over time. Interval data is an important tool for scientists and researchers.

## Difference between Ordinal Data and Interval Data

Ordinal data is a type of data in which the values have a natural order. For example, data that measures how satisfied people are with a product can be Ordinal, with the options being “Very Satisfied,” “Satisfied,” “Neutral,” “Unsatisfied,” and “Very Unsatisfied.” The order of the responses offers information about the intensity of the feeling (e.g., “Very Satisfied” is more intense than “Satisfied”). Interval data is a type of data in which the values have an equal interval between them.

An example of Interval data would be temperature because there is an equal interval between each degree on the Fahrenheit or Celsius scales. Unlike Ordinal data, Interval data does not have a natural order, so we cannot say that one value is “greater than” or “less than” another value. For example, we can say that it is hotter when the temperature is 95°F than when it is 60°F, but we cannot say that 95°F is twice as hot as 60°F.

## Conclusion

In this blog post, we’ve outlined the difference between ordinal data and interval data. Ordinal data is a type of categorical data that can be ranked but doesn’t have an inherent order. Interval data measures differences in magnitude between two points on a scale, making it quantitative. Understanding the difference between these two types of data is important for anyone working with statistics or trying to understand research results.
