How do you calculate the standard deviation of many values if the values have errors associated with them? I have set up columns beside each column of recorded values with the error, so +/- 2 for example, and now I need to run a standard deviation of these numbers. Is it possible to include the errors in this calculation?

Round to nearest half hour?
Use =MROUND(A2,"0:30") to round to nearest half hour. Use =CEILING(A2,"0:30") to round to next half hour.
