Large samples (more than 300) to calculate standard error of reference values- simply a guide or a plain explanation.
Thanks!
standard error of values or some estimator ?
for example standard error of sample average, if you are estimating your population average using the sample average
In regression, to calculate standard error, you must have historical or true values and predicted values t
You will get the difference between each pair of historical and predicted value
You must square this difference
You must get the sum of the squared differences
You will divide this sum by n-1
You will get the square root of this quotient
You have the standard error
Standard error is not an accepted term in the vocabulary of metrology, because there is no generally accepted definition. If your measurements are in error, they should be corrected rather than standardized.
