3. HydroGrow LED SOL-6. The SOL-6 is a 300 watt grow light comprised of 50W integrated LED chips and square fusion reflectors. This light, though it consumes only 300W of electricity, has a PAR output that matches 600W HPS lights.
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.
You can compute the t-statistic to get the 95% confidence limits on the measurement. This will be a range where you can be reasonably certain that the true value lies. If your average is 5 and the 95% limits are 4 to 6, you can claim that the true value is between 4 and 6. Here is where it gets confusing. You can calculate the averages for your drug and placebo group and then compute a confidence level for the difference.
