Hello,I'm checking the similarity of two methods for my research (a gold-standard method and another one which I need to check if it’s eficiente compared to the gold-standard) with student t test. I have the following datas (N=3): method 1 (gold-standard): 120, 347, 116; method 2: 2603, 5203, 25011;The result of one-tailed, independent samples student t test is p=0.11, which is bigger than 0.05. So the test says that there's no significance differece between the two methods, but they are clearly different. The t test is giving me a false result due to the small N number? Should I use another statistic test?
Thanks.
