Difference between Grouped Data and Ungrouped Data

Difference between Grouped Data and Ungrouped Data

When it comes to data, there are two main types: grouped data and ungrouped data. Grouped data is where each observation is put into a group according to some characteristic, while ungrouped data is where each observation is a separate entity. Each type of data has its own benefits and drawbacks, so it’s important to understand the difference between them when you’re working with data. In this blog post, we’ll discuss the difference between grouped and ungrouped data, and we’ll give some examples of how each type can be useful. Stay tuned!

What is Grouped Data?

  • Grouped Data is a statistical concept that is used to systematically display data that has been collected. Grouped Data is extremely useful as it can show large and complex datasets in an understandable way.
  • Grouping the data helps researchers gain insights into how different variables relate to each other and produce visual representations of the information so it is easier to grasp.
  • Grouping the data can also help identify trends, outliers, and interesting correlations between different categories within the dataset, allowing a further understanding of large datasets than what would be available if analyzing individual points of data. Grouped Data has become an increasingly popular tool for researchers trying to make sense of vast amounts of information.

What is Ungrouped Data?

Ungrouped data, also known as raw data, is unorganized numerical information that has not been sorted into different categories or groups. Ungrouped data allows you to see the individual values and compare them side-by-side, which can be useful for any number of statistical analyses. This type of data gives a much better picture than grouped data, which organizes numbers into categories for easier interpretation. Ungrouped data may take longer to analyze, but it ultimately yields much greater insight into the nature of a phenomenon.

Difference between Grouped Data and Ungrouped Data

Grouped data and ungrouped data are two distinct ways of representing information.

  • Grouped data is categorized into intervals or categories, such as “ages 0-10,” “11-20,” and so on.
  • This allows for a clearer understanding of the relationship between different variables in the data set, as well as trends that can be easily identified with this type of structure.
  • Ungrouped data has no specific grouping and is simply listed out without any order.
  • It still provides useful information but requires more effort to interpret it properly as it lacks the organization of Grouped Data.

Understanding the difference between Grouped Data and Ungrouped Data can assist in maximizing the advantages of both types to better analyze an issue or provide meaningful insights into a topic.


Grouped data is when the observations are put into categories. Ungrouped data is when there are no categories and each observation stands alone. The difference between grouped data and ungrouped data can be seen in a bar chart or histogram. In a bar chart, the bars will be taller if there is more grouped data because it takes up more space on the graph. If there was only ungrouped data, then all of the bars would be the same height because they would all represent one observation. A histogram shows how much grouped or ungrouped data there is by using rectangles instead of bars.
