It allows you to understand, or comprehend the average fluctuation to the
average. example: the average height for adult men in the United States is about
70", with a standard deviation of around 3". This means that most men (about
68%, assuming a normal distribution) have a height within 3" of the mean (67"-
73"), one standard deviation, and almost all men (about 95%) have a height
within 6" of the mean (64"-76"), two standard deviations.
In summation standard deviation allows us to see the 'average' as a whole.

What does the sample standard deviation best estimate?
The standard deviation of the population. the standard deviation of the population.
What is standard deviation of 155.45?
The standard deviation is 0.
What is the standard deviation of a standard normal distribution?
The standard deviation in a standard normal distribution is 1.
What is the standard deviation of 9?
You need more than one number to calculate a standard deviation, so 9 does not have a standard deviation.
What is the symbol for standard deviation?
The symbol for standard deviation is sigma , σ.
What are the assumptions of standard deviation?
The standard deviation is the standard deviation! Its calculation requires no assumption.
What does the sample standard deviation best estimate?
The standard deviation of the population. the standard deviation of the population.
What is standard deviation of 155.45?
The standard deviation is 0.
If quartile deviation is 24. find mean deviation and standard deviation?
Information is not sufficient to find mean deviation and standard deviation.
What is the relationship between standard deviation and variance?
Standard deviation is the square root of the variance.
What is the standard deviation of a standard normal distribution?
The standard deviation in a standard normal distribution is 1.
What is the difference between standard error of mean and standard deviation of means?
Standard error of the mean (SEM) and standard deviation of the mean is the same thing. However, standard deviation is not the same as the SEM. To obtain SEM from the standard deviation, divide the standard deviation by the square root of the sample size.
Why do we need the standard deviation?
The standard deviation is a measure of the spread of data.
What is the standard deviation of 9?
You need more than one number to calculate a standard deviation, so 9 does not have a standard deviation.
Difference Standard Deviation of a portfolio?
difference standard deviation of portfolio
What is the symbol for standard deviation?

What is the standard deviation of 24?
Standard deviation of a single event is 0.
