You cannot. If you are told the standard deviation of a variable there is no way to tell whether that was derived from grouped or ungrouped data.

Differing from standard deviations, the coded deviation method finds the mean of grouped data from the assumed mean using unit deviations. This is a shorter way to find the mean.

If the observations are grouped together into classes, then the number of observations for each class gives the grouped frequency distribution (FD). This kind of FD is particularly important when the data are continuous so that you are likely to have very small frequencies for a very large number of values.

It is a grouped frequency table.

Categorical data is the statistical data type consisting of categorical variables or of data that has been converted into that form, for example as grouped data.

Simplest terms, it means that the sample values are grouped closely together. Another way of saying it is that the range of values is small. The plot will be a leptokurtic plot (peaked).

Aggregate data is data combined from multiple measurements. When this happens, the grouped observations are summarized based on those observations.

Yes, but it rather pointless. The mean deviation for any data set will, by definition, be 0. Grouping may make it slightly different from 0 but this statistic has little, if any, useful properties.

Rather than have frequencies of observations allocated to each observed value, grouped data allocates them to a range (or group) of values.

When observations are grouped into class intervals, the interval that contains the most frequently occurring value is known as the modal class.
