How to calc the standard deviation when the data points vary in weight?












0












$begingroup$


I have a table of data like the following:



1st Data Point, is 10% sugar content measured over a 3 litre amount of orange juice

2nd Data Point, is a 15% sugar content measured over a 1 litre amount of orange juice

3rd Data Point, is a 5% sugar content measured over a 2.5 litre amount of orange juice



How do I work out what the standard deviation of the sugar content would be if the data points are of 'n' litres?
