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
Add all the data together and then divide the sum by the number of data points. For example, 3, 4, 5, 6, 7 Sum is 25 There are 5 numbers or data points which combined to make that sum The mean or arithmetic average is 25/5 = 5
The mean is like the average, all of the numbers in a data set added up and divided buy the number of numbers in the data set.
The mean. Strictly, the arithmetic mean.
The difference between the largest and smallest numbers in your data set.
That's the mean ('average') of the numbers in the dataset,divided by the number of pieces of data.
When there are a variety of different numbers numerical data varies. -RJC

You take all the numbers in the data and add them. Then you divide by how many numbers are in the data. :)
to find the mean of a set of numbers you have to find the total sum of the data divided by the number of addends in the data.
Combined means the addition of numbers.. The combination of 6 and 8 is 14 6 + 8 = 14
(10,10,30,30,30,50,50) (20,20,30,30,30,40,40) These two sets have the same mean, median and mode.
The mean of a number is the average of a group of numbers. To find the mean you must add up all of the numbers in a data set. Then you take that number and divide it by the number of numbers you have in the data set. This will give you the mean.
The answer depends onwhat you mean by negative numbers: negative integers, negative rationals, or negative reals?what you mean by "combined with". The union of sets, a sum, multiple or some other Cartesian or cross product.
