Two numbers are needed to find a mean.

There is no smallest number and no biggest number. Given any big number, however big, it is always possible to find one that is bigger (and the same with the smallest).
The mean of a number is the number itself. Finding the mean of one number serves no purpose whatsoever. So, for example, the mean of 5 is 5.
To find the mean, you add up all the numbers and divide that total by the number of numbers you have. With only one number, the mean will always be that number.
One can find statistics on the number of big rig accidents per year, the frequency, and percentage. Most are annual statistics, although there are some bi-annual and cumulative statistics.
You need at least two quantities to find a mean. With only one value, the average would be that number and the mean would be meaningless.
