The average true range is an N-day smoothed moving average (SMMA) of the true range values.Wilder recommended a 14-period smoothing.he range of a day's trading is simply. The true range extends it to yesterday's closing price if it was outside of today's range. The true range is the largest of the: 1  Most recent period's high minus the most recent period's low. 2  Absolute value of the most recent period's high minus the previous close.
Go directly to Critical Values. REFERENCE RANGES. Reference Ranges (ânormal limitsâ) are usually determined by taking either the lowest and highest values (range) of results obtained on a normal population, the mean 2 standard deviations (S.D.) of the values obtained on a large population or the central 95% range.o directly to Critical Values.
