Say we have a bunch of numbers like 9, 2, 5, 4, 12, 7, 8, 11. To calculate the standard deviation of those numbers: 1  1. 2  Work out the Mean (the simple average of the numbers). 3  2. Then for each number: subtract the Mean and square the result. 4  3. Then work out the mean of those squared differences.5  4. Take the square root of that and we are done!o calculate the standard deviation of those numbers: 1  1. 2  Work out the Mean (the simple average of the numbers). 3  2.

Best Answer: The .925 does mean sterling silver and the FB may be a Hallmark. You did not state what is on the medallion so I don't know where it was made. On some silver items the FB stands for Franz Bibus a Czech silversmith.
Bub Definition. What Does Bub Mean. If she says my bub that means my guy/man/boyfriend/husband but if you just say hey bub, what do you think you're doing or that bub over there it's saying guy or pal like if you were to say hey pal what do you think you're doing or that guy over there.
