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 standard deviation of these set of numbers 6 7 7 12 12 11 9 9 8 4 6 13 14?
For 6 7 7 12 12 11 9 9 8 4 6 13 14: σ=3.0947
What is the mean absolute deviation of this set of numbers 3 9 27 81?
mean | 30 median | 18 standard deviation | 35.496
What is the average deviation to numbers 6 1 4 3 4 1 2 9 5?
Standard deviation = sqrt(variance) Variance = E[X2] - E[X]2 E[X] = sum(X)/n = 35/9, so E[X]2 = 1225/81 E[X2] = sum(X2)/n = 189/9 = 1701/81 Variance = 476/81 Standard deviation = sqrt(476/81) ~ 2.42

Compute the variance and standard deviation of the following sample data:5 9 10 2 7 9 14?
mean =(5+9+10+2+7+9+14)/7=8 s^2 = Variance = (1/7){(5-8)^2+(9-8)^2+(10-8)^2+(2-6)^2+(7-8)^2+(9-8)^2+(14-8)^2}=14.6666 Standard deviation =s= sqrt(14.6666)=3.8297

The range is 9 and 3.01 is the standard deviation.
The weights of nine men have a mean of 175 and a standard deviation of 15 what is the standard error of the mean?
(15/sqroot(9))=5 So it is 5
How do you create data set with larger standard deviation?
Standard deviation is the square root of the sum of the squares of the deviations of each item from the mean, i.e. the square root of the variance. In order to increase the standard deviation, therefore, you need to increase the average deviation from the mean. There are many ways to do this. One is to move each item further away from the mean. For example, take the set [2, 4, 4, 4, 5, 5, 7, 9]. It has a mean of 5 and a standard deviation of 2.14. Multiply each item by 2.2 and subtract 5, giving the set [-1.3, 2.9, 2.9, 2.9, 5, 5, 9.2, 13.4], effectively moving each item 10% further away from the mean. This still has a mean of 5, but the standard deviation is 4.49.
What does it mean when the standard deviation is 1?
A standard deviation is a statistical measure of the variation there in a population or group. A standard deviation of 1 means that 68% of the members of the population are withing plus or minus the value of the standard deviation from the average. For example: assume the average height of men is 5 feet 9 inches, and the standard deviation is three inches. Then 68% of all men are between 5' 6" and 6' which is 5'9" plus or minus 3 inches. [Note: this is only to illustrate and is not intended to be a real/correct statistic of men's heights.]
