How many of you use the 95th Confidence Interval in your “Data Sampling”?
Whether it’s personal sampling, area sampling, or any sampling looking for safety data, do you attempt to achieve the 95th confidence interval?
A 95% confidence interval is a range of values, calculated from sample data, that is likely to contain an unknown population parameter. It means if you repeat an experiment many times, 95% of the calculated intervals will hold the true value.
