Why the minimum and maximum values for the grouped data are different from the minimum and maximum values for the raw data?
The minimum and maximum values for grouped data can differ from those of raw data because grouped data summarizes ranges of values rather than individual observations. In grouping, the actual minimum and maximum values may fall within a range, leading to a representation that does not capture the true extremes of the raw data. Additionally, if the grouping intervals are not small enough, they may miss outliers or extreme values that exist in the raw dataset. Thus, the aggregated nature of grouped data can obscure the precise minimum and maximum values present in the raw data.
What is continuous grouped data?
In continuous grouped data the data is collected continuously and in groups. Data collected is in class intervals the actual data values are not visible.
What do you call data if organized with several values together?

Is the mean of the grouped data is equal to the mean of ungrouped data?
Suppose you compare the mean of raw data and the mean of the same raw data grouped into a frequency distribution. These two means will be
What is definition of grouped data?
Grouped means the grouping of relevant data after analysis. When raw data is analyzed in proper and meaningful way then its transformed into groups and these groups are known as grouped data.
What is an 'ungrouped frequency table'?
A frequency distribution of numerical data where the raw data is not grouped.

How can you change the data in to raw data?
From Processed Data to Raw (Reverse Engineering) a) Find the Original Source Start by locating the original data file, whether it’s from a sensor, a form, an export, or a system log. For instance, instead of relying on a monthly sales report, grab the transaction log straight from the POS system. b) Remove Any Processing or Formatting Make sure to undo any filters, formulas, or pivot tables in Excel. Don’t forget to delete calculated fields like averages or percentages, and restore any rows and columns that might have been hidden or trimmed. c) Convert to Plain Text To strip away formatting, copy and paste the data into Notepad or save it as a .csv or .txt file. In Excel, you can use “Paste Special > Values” to eliminate formulas. From Printed or Visual Data If you’re working with a printed report or graph, you can use OCR (Optical Character Recognition) tools to pull out the raw text. Alternatively, you can manually rebuild the dataset by entering the values into a spreadsheet, or you could simply ask the source (like the analyst or system) for the original file. Export Raw Data from a Tool Most platforms, such as Google Forms, CRMs, or web analytics tools, offer a way to export raw data. Look for options like “Download CSV,” “Export all responses,” “Raw export,” or “Download logs.” This will provide you with the data in its most unprocessed form.
Can a grouped of data be grouped?
Not sure what a "grouped of data" means!
What are the categories by which data are grouped?
Data can be grouped or ungrouped. The categories data are grouped in depend on the data. For example, data collected about people could be grouped as male/female, by ages, or some other common characteristic. Data collected about dogs could be grouped by breed of dog, age, long hair/short hair, or size.
Definition of ungrouped data?
Ungrouped data is data that is not grouped in a specific order. Grouped data is a set of data that has unique characteristics in common.
What is continuous grouped data?
In continuous grouped data the data is collected continuously and in groups. Data collected is in class intervals the actual data values are not visible.
If data are organized with several values together the result is?
The result is a collection of grouped data.
