Yes SD is ofcourse measure of precision
The more precise a result, the smaller will be the standard deviation of the data the result is based upon.
Standard error is a measure of precision.
No. The average of the deviations, or mean deviation, will always be zero. The standard deviation is the average squared deviation which is usually non-zero.
standard deviation is best measure of dispersion because all the data distributions are nearer to the normal distribution.
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.
precision
Units of measure do follow the standard deviation.
Standard deviation is a measure of the spread of data.
The more precise a result, the smaller will be the standard deviation of the data the result is based upon.
The standard deviation is a measure of the spread of data.

1. Standard deviation is not a measure of variance: it is the square root of the variance.2. The answer depends on better than WHAT!
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.
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.
the standard deviation of the sample decreases.
