Calculated confidence in the cq value is low

WebJun 1, 2024 · SD of the data can be calculated in either log (Cq values) or linear scale (relative quantities) and does not assume any particular distribution. In each case, SD reflects the average difference of the measured values to the mean in the same scale. In contrary to SD, calculation of the confidence interval assumes normal distribution.
