Matched Pairs T-test in SAS
{"Image DocumentName": "Matched Pairs T-test in SAS", "Image ImageDescription": "We want to determine whether a weekend study session improves students\u2019 test scores. Six students are given a math test before the session, then they are re-tested after the weekend training. This is a matched pairs t-test, because the same subjects are being measured before and after some intervention. Ho: \u00b5before = \u00b5after. Ha: \u00b5before \u2260 \u00b5after. Again, before we can analyze the data, we have to determine whether we can assume the data come from a normal distribution.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
