the mean is the average of the numbers. Since the mean of the 4 numbers is 24.5, the sum of the numbers is 4 x 24.5 = 98. If you add 26 the sum is 98 + 26 =124, and the new mean is the average of the 5 numbers, or 124/5 = 24.8
mean does not mean the center of the data
what do you mean by data assembly?
The mean of a set of data is the sum of that data divided by the number of items of data.
The mean and median become smaller, the mode does not change.
Mean data are observations whose values are equal to the mean of the data set. By default it is the arithmetic mean but it could be the geometric or harmonic mean - if those measures are more appropriate.
The mean increases by 10.
They are best for showing sets of data that just have an amount. This usually happens with a survey.
It changes
The mean of the new data set is shifted from the mean of the original set, in the direction of the added cluster. We note that the same would be true if only a single new element were added.

no. Some mean is a number from the data but some mean is completely different from its data.
Its mean incomplete data or the data upon which we can not rely totally.
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 mean and median become smaller, the mode does not change.
