Standard deviation of mean, Electrical Engineering

Assignment Help:

For large number of measurements the mean is calculated by taking a sample. Each sample that is taken has a mean. The mean of various sample difference from sample and are known to flow a definite distribution known as distribution of means,

If the parent measurements from which a sample is drawn is distributed normally with mean µ and standard deviation σ, then the mean of sample also  distributed normally with meanµ and the standard deviation =           standard deviation of mean
