The ''mean'' is just another term for average. To find the mean, you must add all of the data together and divide that number by the number of pieces of data. Hope this helped!

The mean of a set of data is also known is the average.
The average of a set of data is known as its "mean."
The mean of a set of data is the sum of that data divided by the number of items of data.
No. Here's one set of data where the mean is not one of the values: a set of 250,000 numbers. 125,000 of them are "1", 125,000 are "3". The mean of this data set is "2", which is not among the data.
no. Some mean is a number from the data but some mean is completely different from its data.
It is misleading to use the mean as a descriptor of a data set when the median or mode would be more representative of the data set as a whole.
When the data set consistys of a single value.
If the set of data are represented by a letter, then the mean is represented by that letter with a bar across its top.
The mode of the data is the number which occurs most frequently in the given set of data.
total marks of data set 1 is 6 x 8 = 48 total marks of data set 2 is 6 x 20= 120 now, the total mean of the combined data set is = (48 + 120) / (6 + 6) = 168 / 12 = 14
MEAN
There is an infinite number of data sets that have a mean of 8. One such set is 7, 8, 9.
