If there is no mean given, you can try finding the median of the data set. The median is the middle value when the data set is sorted in ascending order. If the data set has an even number of values, the median is the average of the two middle values. If the missing number is the median, finding the median will help you identify it.
If there is no mean it is very rare that you will be able to find a missing number. Potentially if you have other numbers and you have a mode you can deduce the missing number by using the mode (if there needs to be one more of a certain number or a certain number cannot be increased in its count of numbers i.e. you can't have more 6's to maintain the current mode).
One reason I can think of why you might not be able to find the mean of numerical data would be if there were missing data points.

The mean of a set of data is the sum of that data divided by the number of items of data.
You cannot.

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. Why can't you find the mean of numerical data? One reason I can think of why you might not be able to find the mean of numerical data would be if there were missing data points.

Add all the numbers and divide it by however many numbers you added, then that's how you get the missing number to help you complete the mean.
Convert it.

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 ''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! ~Maci~
