No.
Mean and median are the measures of central location that always have one value. This is true for a set of grouped or ungrouped data.
The mean.
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
The value is 0.3055
No. They are equal only if the distribution is symmetrical.

Difference (deviation) from the mean.
When the data set consistys of a single value.
No, not always. It depends on the type of data you collect. If it is quantitative data, you will be able to calculate a mean. If it is qualitative data, a mean can't be calculated but you can describe the data in terms of a mode.
A standard deviation of zero means that all the data points are the same value.
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
The least value of the data set is called the minimum.
For different sets of data, the mean would be the summation of all observations, which are normally subdivided by the observation numbers. The mean value would frequently be quoted with standard deviations: mean would describe data central locations then standard deviations illustrate the spread. Substitute dispersion measures include mean variations that are always equal to average absolute deviations from the mean values. It is minimally responsive to the outliers. Hope this helps.
