If the standard deviation decreases does the mean decrease?
Not necessarily. The standard deviation measures (in simplified terms) how different the numbers are from each other, while the mean is their average. If the standard deviation decreases, it means the numbers are closer to each other, it doesn't change how big the numbers are.
Set of 25 numbers has standard deviation 6 then it's variance is?
Square the standard deviation to obtain the variance. The variance is 62 or 36.
What is the standard deviation if all the numbers in a set of data are equal?
It is 0.
What is deviation in statistics?
Deviation, actually called "standard deviation" is, in a set of numbers, the average distance a number in that set is away from the mean, or average, number.
What is the standard deviation for sample numbers 8 9 and 10?
For 8 9 10: σ=1
Why do we need the standard deviation?
The standard deviation is a measure of the spread of data.
What is standard deviation of 19.5364000 8.5264000 0.6724000?
9.47589848 is the standard deviation for those numbers.
Can a standard deviation of 4.34 be correct?
Yes, a standard deviation of 4.34 can be correct. Standard deviation is a measure of dispersion or variability in a data set. It represents the average amount by which individual data points deviate from the mean. Therefore, a standard deviation of 4.34 simply indicates that there is some variability in the data, with data points on average deviating by 4.34 units from the mean.
What is the minimum data required for standard deviation?
The standard deviation is a measure of how spread out the numbers are. Three points is needed to calculate a statistically valid meaningful standard deviation.
How do you use standard deviation?
Standard deviation is a measure of how spread out a set of numbers are from each other. It has a variety of uses in statistics.
If the standard deviation decreases does the mean decrease?
Not necessarily. The standard deviation measures (in simplified terms) how different the numbers are from each other, while the mean is their average. If the standard deviation decreases, it means the numbers are closer to each other, it doesn't change how big the numbers are.

Square the standard deviation to obtain the variance. The variance is 62 or 36.
What is the standard deviation of 51 64 35 74 42 62 34 39 52 77?
15.72683482 is the standard deviation for that set of numbers.
Find standard deviation of nos 45 42 33 38 47 51 35 60?
