Standard deviation helps you identify the relative level of variation from the mean or equation approximating the relationship in the data set. In a normal distribution
1 standard deviation left or right of the mean = 68.2% of the data
2 standard deviations left or right of the mean = 95.4% of the data
3 standard deviations left or right of the mean = 99.6% of the data

How do you find the sample deviation?
You're an idiot. It's standard deviation. Google that for your answer.
How do you find graph median by using standard deviation?
You cannot because the median of a distribution is not related to its standard deviation.
N equals 36 with a population mean of 74 and a mean score of 79.4 with a standard deviation of 18?
Can someone help me find the answer for a sample n=36 with a population mean of of 76 and a mean of 79.4 with a standard deviation of 18?
What does the sample standard deviation best estimate?
The standard deviation of the population. the standard deviation of the population.
Find standard deviation of nos 45 42 33 38 47 51 35 60?
8.919280881 is the standard deviation for those numbers.
If quartile deviation is 24. find mean deviation and standard deviation?
Information is not sufficient to find mean deviation and standard deviation.
Why we calculate standard deviation and quartile deviation?
we calculate standard deviation to find the avg of the difference of all values from mean.,
Is variance the square root of standard deviation?
No, you have it backwards, the standard deviation is the square root of the variance, so the variance is the standard deviation squared. Usually you find the variance first, as it is the average sum of squares of the distribution, and then find the standard deviation by squaring it.
How do you calculate standard deviation with the help of z-score?
A z-score cannot help calculate standard deviation. In fact the very point of z-scores is to remove any contribution from the mean or standard deviation.
How do you find the sample deviation?
You're an idiot. It's standard deviation. Google that for your answer.
How do you find graph median by using standard deviation?
You cannot because the median of a distribution is not related to its standard deviation.
Why would someone need a standard deviation calculator?
A standard deviation calculator allows the user to find the mean spread away from the mean in a statistical environment. Most users needing to find the standard deviation are in the statistics field. Usually, the data set will be given and must be typed into the calculator. The standard deviation calculator will then give the standard deviation of the data. In order to find the variance of the data, simply square the answer.
How do i find sample standard deviation from population standard deviation?
If the population standard deviation is sigma, then the estimate for the sample standard error for a sample of size n, is s = sigma*sqrt[n/(n-1)]
How do you find the standard deviation for data?
Standard deviation calculation is somewhat difficult.Please refer to the site below for more info
Give an example of how to find the standard deviation?
Look at the Wikipedia article on "Standard deviation" - it includes an example right at the beginning.
What are the assumptions of standard deviation?
The standard deviation is the standard deviation! Its calculation requires no assumption.
How do you find highest standard deviation in given number?
Standard deviations are measures of data distributions. Therefore, a single number cannot have meaningful standard deviation.
