Best Answer

In any given set, the mean is the average, which is the total of the numbers divided by how many numbers there are.

Ex. (10, 17, 20, 45, 68)

68 + 45 + 20 + 17 + 10 = 160

There are 5 numbers in this set.

160/5 = 32

The mean is 32.

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.

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.

no. Some mean is a number from the data but some mean is completely different from its data.

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.

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

The mode of the data is the number which occurs most frequently in the given set of data.

MEAN

Th find the mean of a data set, you add up all the values in the data set and divide this sum by the number of data values. For example, the mean for the data set 2, 5, 6, and 7 is given as 2 plus 5 plus 6 plus 7, which is 20. You divide this sum by number of values in the data set, which is 4 to get 5 as the mean.
