The mean of a set of data is also known as the average. To get the average, add all the numbers in a data set up, then take away the number of numbers. eg. data set = 5,6,7,6,6,4,4,3,4,5,4,6. Added = 60 Number of numbers = 12 60/12 = 5 = Average

The answer depends on where, within the sequence, the missing number should have been.

The number keeps being revised. As of 16 January 2011, the number of missing has dropped to 12. Just five days previously, the number of missing was over 90.

# Well, the mean is like the average. So if you had these numbers 5,10,and 15, the mean(average) would be 10. # The median is like the middle number in a set of numbers. So if these were your numbers 3, 54, 66,71,75, 76, 78, 84, 88, 92, 99. The median is 76. # The mode is the number that repeated itself more then once. (there can be more than 1 mode) So if these were your set of numbers, 12, 12, 12, 43, 53, 61, 78, 84, 94, 99,99,99,99. Then your mode would be 99. # The range is the difference between the min. and max. numbers in your set of number. So if your set of numbers were 15,34,57,78,81,97. The range would be 82.
