Factors that affect the sample size
{"Image DocumentName": "Factors that affect the sample size", "Image ImageDescription": "1. Power of the study. The power of a study is the probability of detecting a real difference. In other words, it is same as the probability of making a positive diagnosis when the disease is present. For a good study one should have to take at least 80% power. An increase in the sample size or a greater difference between the control and the test groups leads to an increase in the power of the test.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
