A single observation, such as 50486055535157526145 cannot have a standard deviation cube test compressive result.
You cannot calculate standard deviation for objects such as concrete cubes - you can only calculate standard deviation for some measure - such as side length, surface area, volume, mass, alkalinity or some other measure.
Square the standard deviation and you will have the variance.
it is in arithmetic
You need more than one number to calculate a standard deviation, so 9 does not have a standard deviation.

Standard deviation is a statistical concept and not applicable to concrete.
we calculate standard deviation to find the avg of the difference of all values from mean.,
Square the standard deviation and you will have the variance.

Standard deviation = square root of variance.
Standard deviation is how much a group deviates from the whole. In order to calculate standard deviation, you must know the mean.
In the same way that you calculate mean and median that are greater than the standard deviation!
You cannot because the standard deviation is not related to the median.
A z-score cannot help calculate standard deviation. In fact the very point of z-scores is to remove any contribution from the mean or standard deviation.
