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.
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.
In statistics, ungrouped data refers to raw data points that are presented individually, allowing for detailed analysis and precise calculations, such as mean and median. In contrast, grouped data is organized into classes or intervals, which simplifies representation and analysis, particularly for larger datasets, but may obscure specific values. Grouped data is often displayed in frequency tables or histograms, while ungrouped data is typically shown in lists or scatter plots. Each type has its own advantages, depending on the context and goals of the analysis.

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
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.
A frequency distribution of numerical data where the raw data is not grouped.

Not sure what a "grouped of data" means!
Processing.
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.
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.
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.
The result is a collection of grouped data.
