统计上学过,但是多年不用记不清了 google了一下 A t-test is any statistical hypothesis test in which the test statistic follows a Student's t distribution, if the null hypothesis is supported. It is most commonly applied when the test statistic would follow a normal distribution if the value of a scaling term in the test statistic were known. When the scaling term is unknown and is replaced by an estimate based on the data, the test statistic (under certain conditions) follows a Student's t distribution. 网址http://en.wikipedia.org/wiki/Student's_t-test |
