What is the standard form of a perfect square?
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
What is the equation for standard deviation?
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.
How do you convert variance of 10.8 square inches into standard deviation?
Standard deviation = square root of variance.
What is the mean and standard deviations and the standard normal distribution?
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.
How do you find standard deviation?
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
