Thus , while these two cities may each have the same average maximum temperature , the standard deviation of the daily maximum temperature for the coastal city will be less than that of the inland city as , on any particular day , the actual maximum temperature is more likely to be farther from the average maximum temperature for the inland city than for the coastal one .	However , the standard deviation of the daily high temperature for the coastal city will be less than that of the inland city .
The practical value of understanding the standard deviation of a set of values is in appreciating how much variation there is from the average ( mean ) .	The use of understanding the standard deviation of a set of values is in knowing how large a difference from the `` average '' ( mean ) is expected .
In finance , standard deviation is often used as a measure of the risk associated with price-fluctuations of a given asset ( stocks , bonds , property , etc. ) , or the risk of a portfolio of assets ( actively managed mutual funds , index mutual funds , or ETFs ) .	It can also mean the risk that a group of prices will go up or down ( actively managed mutual funds , index mutual funds , or ETFs ) .
A low standard deviation indicates that the data points tend to be very close to the mean ( also called expected value ) ; a high standard deviation indicates that the data points are spread out over a large range of values .	A high standard deviation means that the numbers are spread out .
For example , consider a population consisting of the following eight values : These eight data points have the mean ( average ) of 5 : First , calculate the difference of each data point from the mean , and square the result of each : Next , calculate the mean of these values , and take the square root : This quantity is the population standard deviation , and is equal to the square root of the variance .	Consider a group having the following eight numbers : These eight numbers have the average ( mean ) of 5 : To calculate the population standard deviation , first find the difference of each number in the list from the mean .
Three standard deviations account for 99.7 percent of the sample population being studied , assuming the distribution is normal ( bell-shaped ) .	Three standard deviations include all the numbers for 99.7 % of the sample population being studied .
For example , the margin of error in polling data is determined by calculating the expected standard deviation in the results if the same poll were to be conducted multiple times .	For example , the standard deviation is used to find margin of error in opinion poll numbers .
Dividing by n − 1 gives a better estimate of the population standard deviation than dividing by n . As a slightly more complicated real-life example , the average height for adult men in the United States is about 70 inches , with a standard deviation of around 3 inches .	A slightly harder , real life example : The average height for grown men in the United States is 70 '' , with a standard deviation of 3 '' .
This means that most men ( about 68 percent , assuming a normal distribution ) have a height within 3 inches of the mean ( 67-73 inches ) - one standard deviation - and almost all men ( about 95 % ) have a height within 6 inches of the mean ( 64-76 inches ) - two standard deviations .	A standard deviation of 3 '' means that most men ( about 68 % , assuming a normal distribution ) have a height 3 '' taller to 3 '' shorter than the average ( 67 '' -73 '' ) - one standard deviation .

Because all three of the G.B Sowerbys published extensively on the subject of conchology , it is not easy even for professional taxonomists to unravel which of the three `` G.B. Sowerbys '' is meant in a particular citation when the numbering system G.B. Sowerby I , II , or III is not used .	Even for professional taxonomists it is difficult to know which of the three `` G.B. Sowerbys '' is meant in a particular citation .
