You would need to take repeated samples, find their median and then calculate the standard error of these values.

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.
Gross volume is the volume at actual condition whereas standard volume is at standard Pressure/Temperature condition.
the purpose and function of standard error of mean
You calculate the standard error using the data.
You would need to take repeated samples, find their median and then calculate the standard error of these values.
To compute the standard error in refractive index from a graph, calculate the standard deviation of the data points and divide it by the square root of the sample size. This will give you the standard error in your refractive index measurement.
Standard error of the sample mean is calculated dividing the the sample estimate of population standard deviation ("sample standard deviation") by the square root of sample size.
to ensure your experiment is precise and to prevent error to happen during experiment
(0.6745 * Standard deviation)/ (n^1/2) :)
To calculate the volume at standard conditions, we can use the ideal gas law equation, PV = nRT. First, calculate the number of moles of xenon gas using the given conditions. Then, using the molar volume at STP (22.4 L/mol), calculate the volume of xenon gas at standard conditions.
To calculate the volume of natural gas in standard cubic meter at standard pressure, you can use the ideal gas law equation: V = nRT/P, where V is the volume in standard cubic meters, n is the number of moles of gas, R is the ideal gas constant, T is the temperature in Kelvin, and P is the standard pressure. Given that standard pressure is typically defined as 1 atmosphere or 101.325 kPa, you can plug in these values along with the temperature and number of moles of gas to calculate the volume of natural gas in standard cubic meter at standard pressure.

Standard error is random error, represented by a standard deviation. Sampling error is systematic error, represented by a bias in the mean.
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.
It would help to know the standard error of the difference between what elements.
