To find the upper bound of an error band, simply add the error to the average. STEP 2: FIND THE UPPER AND LOWER BOUNDS OF EACH ERROR BAND
In the example above, I use standard error but you could also use a confidence interval, standard deviation, variance, or any other measurement of uncertainty.īelow the rows containing the averages and standard deviations, we will add additional rows for the upper and lower bound of each error band.
The rows should contain the averages and uncertainty measurements associated with each condition and the columns should contain measurements over time.
