to square a number multiply it by itself to find the square root start withh your number and try to find a number that multplies itself to get that number then you have your square root ex.)5*5=25 or 25/5=5
Standard deviation is equal to the square root of the variance. To arrive at this work out the mean, then subtract the mean and square the result of each number. Then work out the mean of those squared differences and take the square root of that.
Standard deviation = square root of variance.
Mean is the average, sum total divided by total number of data entries. Standard deviation is the square root of the sum total of the data values divided by the total number of data values. The standard normal distribution is a distribution that closely resembles a bell curve.
First, you need to determine the mean. Then, subtract the mean from every number you have. The SQUARE all your numbers. Add up all of the resulting squares to get their total sum. Divide by one less then the total numbers you have (if you have 6 numbers you will divde by five) To get the standard deviation, just take the square root of the resulting number
The standard form of a complex number is a+bi. So the standard form of the negative square root of 5i is 0-√(5i).

no it is not possible because you have to take the square of error that is (x-X)2. the square of any number is always positive----------Improved answer:It is not possible to have a negative standard deviation because:SD (standard deviation) is equal to the square of V (variance).
Standard deviation is equal to the square root of the variance. To arrive at this work out the mean, then subtract the mean and square the result of each number. Then work out the mean of those squared differences and take the square root of that.
One can purchase a square rug in Houston from a number of retailers. One can buy them from 'Home Depot', 'Rug Mart Houston' and 'Carpet Giant Houston'.
The sample standard deviation (s) divided by the square root of the number of observations in the sample (n).
The square of the standard deviation is called the variance. That is because the standard deviation is defined as the square root of the variance.
Euro pillows are standard in Europe and differ a little in size from a standard American pillow. Euro pillows are typically 26"x26" making them square in comparison to a rectangular American pillow.
I found a white square toilet seat with a 10" bolt at PlumbingSupply.com
Yes, the variance of a data set is the square of the standard deviation (sigma) of the set. This means that the variance is always a positive number, even though the data might have a negative sigma value.
No. Standard deviation is the square root of a non-negative number (the variance) and as such has to be at least zero. Please see the related links for a definition of standard deviation and some examples.
You can but you may have to purchase it online since it is not the standard size. I'd check out amazon.com for sure special order umbrella size, should have it there for you.
