How do you find the average or mean in a set of data?

First, you add all of the numbers in the set together. Then, you divde the sum by however many numbers there are in the set of data. Your quotient is the average/mean.

Explain how you find the mean of a set of data?

To answer this question I will use an example. Data set: 10, 20, 30, 40, 50. First find the sum of all the numbers...so 10+20+30+40+50= 150. Then you take the sum (150) and divide it by the number of numbers in the data set. So 150 divided by 5 (the number of numbers in this data set) = 30. 30= the mean of the above data set. Finding the mean is pretty simple. :)

Is it true that in large data sets the mean is always one of the data values?

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.

When is it misleading to use the mean as a descriptor of a data set?

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.

How can you find the assumed mean of grouped data?

find assumed mean data is 46,55,52,59,63,47,56,50,51,55 ,
