[求助] Student-t and F tests是什么意思,什么分析方法

有一审稿意见是:A reported method should be used for the determination of morin in real sample for comparison with this electrochemical method. And for the comparison of the proposed method with the already published methods Student-t and F tests should be used. The obtained results should be reported with their explanations.请问这是什么意思啊,重点是 Student-t and F tests是什么意思,什么分析方法,请教一下大家

没做过,以下供参考:
The t-test is used to determine whether the difference between two means is significant. The null hypothesis tested in all four types of t-test is that “the difference between two population means is zero”. When the alternative hypothesis is “the difference is not equal to zero”, the two-tailed probability should be compared against the given significance level α (usually 0.05). If the calculated probability is greater than α, then the null hypothesis cannot be rejected. Otherwise, we can conclude that the two means are significantly different. In this case, the confidence interval for the difference will not enclose 0. When the alternative hypothesis is a difference in one direction (i.e. one mean is greater or less than the other), then the one-tailed probability is compared against α.

The F-Test is used to compare variances or standard deviations of two samples. The null hypothesis tested is “the two populations have equal variances”. Columns selected for this test need not be equal in size. Output displays the F‑value, degrees of freedom, the right and two-tailed probabilities from the F-distribution and the confidence interval for the specified confidence level.
