![]() 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. This is done to get a more condensed form of data. When we assemble raw data into a number of classes, the resultant data is the grouped data. What is Frequency Distribution?Ī frequency distribution is the arrangement of data in tabular form which represents the frequency, with which each consecutive value of the variable occurs.Īlso Read: Difference Between Qualitative and Quantitative Data Definition of Grouped Data Here, the number of times each number occurs is called frequency. frequency distribution table for raw data or ungrouped data. Further, for easy understandability of the data, we will present it in tabular form i.e. When the number of observations is large, it becomes monotonous and time-consuming. Plus, the difference between the largest and smallest number is the range. An array is nothing but an arrangement of numerical observations in the order of magnitude. ![]() Well, data given in this form is called arrayed data. Now, you must be wondering – what do we call this type of data? Suppose we want to analyze the women who are above 35 years, the data presented in the above form does not provide sufficient information, such as the highest or lowest age. 55, 35, 296, and so forth, is the value or observation. So, one cannot arrive at any conclusion, unless the data is arranged in a specific order, i.e. It is gathered as individual observations, commonly as a table or range of jumbled values.Īs the data is presented in its actual form, computation, analysis, and interpretation is cumbersome process. It is a collection of observations that are gathered initially during the research by the investigator or obtained from the specified source. Numerical Data available in its authentic form is called ungrouped data. When raw data are grouped into classes, it is termed Grouped data. Prerequisites for the formation of classesĭata that is gathered for the first time during a study or experiment, is called Ungrouped data. ![]() ![]() This write-up will help you in understanding the difference between ungrouped data and grouped data. What is Data?ĭata refers to the fresh information or a set of given facts, in numerical figures collected by individuals or obtained from various sources for a specified purpose.Īlso Read: Difference Between Data and Information On the other hand, grouped data refers to the data which is bundled together in different classes or categories. This is because no summarization or aggregation is possible. In simple words, ungrouped data or raw data is a mere list of numbers that does not convey anything. ![]()
