The mean is 12 and each observation is 8 units away from 12.
Yes it does. The center, which is the mean, affects the standard deviation in a potisive way. The higher the mean is, the bigger the standard deviation.
Standard deviation is a measure of variation from the mean of a data set. 1 standard deviation from the mean (which is usually + and - from mean) contains 68% of the data.
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.
A single number, such as 478912, always has a standard deviation of 0.
Square the standard deviation to obtain the variance. The variance is 62 or 36.
Knowing the formula is helpful. Also, having a data-set to analyze makes the job much easier.
Standard deviation helps planners and administrators to arrive at a figure that could be used to determine a range that can effectively describe a given set of numerical information/data; and based on which a decision concerning a system of those data can be made.
Standard deviation has the same unit as the data set unit.
A single number, such as 478912, always has a standard deviation of 0.
Yes it does. The center, which is the mean, affects the standard deviation in a potisive way. The higher the mean is, the bigger the standard deviation.
Standard deviation is a measure of variation from the mean of a data set. 1 standard deviation from the mean (which is usually + and - from mean) contains 68% of the data.
Standard Deviation tells you how spread out the set of scores are with respects to the mean. It measures the variability of the data. A small standard deviation implies that the data is close to the mean/average (+ or - a small range); the larger the standard deviation the more dispersed the data is from the mean.
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.
Standard deviation is the square root of the variance. Since you stated the variance is 4, the standard deviation is 2.
A single number, such as 478912, always has a standard deviation of 0.
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.
The standard deviation of a single number, as in this question, is 0.
