Definition of Ungrouped Data
Numerical Data available in its authentic form is called ungrouped data. It is a collection of observations that are gathered initially during the research by the investigator or obtained from the specified source. It is gathered as individual observations, commonly as a table or range of jumbled values.
Definition of Grouped Data
When we assemble raw data into a number of classes, the resultant data is the grouped data. This is done to get a more condensed form of data. Data are grouped when the variable stretches over a wide range and there are a large number of observations, and it is not possible to arrange the data in any order, as it consumes a lot of time.
Conclusion
Ungrouped data, as already said, is the data collected from the respondents in its actual form or as it is. The division of data into different classes is called grouped data.
What is Ungrouped Data?
Ungrouped data which is also known as raw data is data that has not been placed in any group or category after collection. Data is categorized in numbers or characteristics therefore, the data which has not been put in any of the categories is ungrouped. For example, when conducting census and you want to analyze how many women above the age of 45 are in a particular area, you first need to know how many people reside in that area.
Why is ungrouped data preferred?
When collecting data, ungrouped data is preferred because the information is still in its original form. It has not been tampered with by classification or subdivision. However, when analyzing it and drawing graphs, grouped data is preferred because it is simple to interpret.
What is qualitative data?
On the other hand, qualitative data is used to describe information in words. After collecting data, it needs to be organized hence the need to separate grouped data from ungrouped data. Both are useful forms of data but the difference between them is that ungrouped data is raw data. This means that it has just been collected ...
Why is ungrouped data considered raw information?
The number of individuals residing in that area is ungrouped data or raw information because nothing has been categorized. We can therefore conclude that ungrouped data is data used to show information on an individual member of a sample or population. Some of the advantages of ungrouped data are as follows;
Why are frequency tables used?
Frequency tables are used to show the information of grouped data whereas in the case of ungrouped data, the information appears like a big list of of numbers. This is due to the fact that the information is still raw.
What are the two types of data?
It can be in form of numbers, words, measurements and much more. There are two types of data and these are qualitative data and quantitative data . The difference between the two types of data is that quantitative data is used to describe numerical information.

What is ungrouped data?
When the data has not been placed in any categories and no aggregation/summarization has taken placed on the data then it is known as ungrouped data. Ungrouped data is also known as raw data.
What is the second quartile of the data?
NOTE: The second quartile is equal to the median of the data .
What is the median of a dataset?
NOTE: For an odd number of the dataset, the median is the middle value. For an even number of the dataset, the median is the average of the two middle values.
Do both curves have the same mean?
Both curves have the same mean but their scatter is different.
Why do we use ungrouped frequency distributions?

What type of frequency distribution is used to display the frequency of each individual data value?
Another type of frequency distribution we could create is an ungrouped frequency distribution , which displays the frequency of each individual data value rather groups of data values.
How to visualize frequency distribution?
The easiest way to visualize the values in an ungrouped frequency distribution is to create a frequency polygon, which displays the frequencies of each individual value in a simple chart.
What is grouped frequency table?
The grouped frequency table is a statistic method to organize and simplify a large set of data in to smaller "groups." When a data consists of hundreds of values, it is preferable to group them in a smaller chunks to make it more understandable. The group frequency distribution is essentially a table with two columns.
