Hi, I would like your suggestions on calculation of Sample Size. Attached is a sample spreadsheet that has 4 columns. Details of the first 2 columns will be provided and based on the provided data we will need to research and enter the appropriate findings in the Third column. The fourth is a Confidence level where in it needs to be answered by a Yes or a No. Its either they are confident in their research or they are not confident. There could be thousands of such data that needs to be researched. My question here is how do we determine the Best sample size that needs to be selected to perform a QA and get optimized results. Thanks, Krishna Murthy CHVG SSD.xls
