- Standard Deviation

- Why Take A sample?
The Standard Deviation is a measure of how spread out numbers are.You might like to read this simpler page on Standard Deviation first.But here we explain the formulas.The symbol for Standard Deviation is σ (the Greek letter sigma).Say what? Please explain!OK. Let us explain it step by step. 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. Work out the Mean (the simple average of the numbers) 2. Then for each number: subtrac...
But wait, there is more ...... sometimes our data is only a sample of the whole population.We can still estimate the Standard Deviation.But when we use the sample as an estimate of the whole population, the Standard Deviation formula changes to this:The important change is \\"N-1\\" instead of \\"N\\" (which is called \\"Bessel's correction\\"). OK, let us now calculate the Sample Standard Deviation:
When we used the whole population we got: Mean = 7, Standard Deviation = 2.983...When we used the sample we got: Sample Mean = 6.5, Sample Standard Deviation = 3.619...Our Sample Mean was wrong by 7%, and our Sample Standard Deviation was wrong by 21%.
Mostly because it is easier and cheaper.There is a nice quote (possibly by Samuel Johnson): \\"You don't have to eat the whole ox to know that the meat is tough.\\" This is the essential idea of sampling. To find out information about the population (such as mean and standard deviation), we do not need to look at all members of the population; we only need a sample. But when we take a sample, we lose some accuracy.
Mar 04, 2020 · The future value formula helps you calculate the future value of an investment (FV) for a series of regular deposits at a set interest rate (r) for a number of years (t). Using the formula requires that the regular payments are of the same amount each time, with the resulting value incorporating interest compounded over the term.
"Magic Formula" is a term used to describe the investment strategy explained in The Little Book That Beats the Market. There is nothing "magical" about the formula, and the use of the formula does not guarantee performance or investment success.
