Continuous measurements provide the greatest possible information content (within the boundaries of measurement . To calculate yield, subtract the calculated value of defects from the total opportunities, then divide by the total opportunities & express the result in percentage. First of all the most basic thing is that sigma level is calculated differently for discrete and continuous type of data. In the previous method, we saw the approach to find out the value of 6 sigma for discrete data. The percentage of products or services without defects is the yield.
