How to interpret the P-value, the result of the T-test The P-value has many complex statistical meanings, but for practical purposes, it represents the probability that there is no difference between the two data groups selected.
The statistical tests proposed in the differential expression tool in XLSTAT are traditional parametric or non-parametric tests: Student t-test, ANOVA, Mann-Whitney, Kruskal-Wallis.
As a result, this analysis provides a conservative alternative to directly reporting the results from multiple t-tests across pre-specified time-bins(e.g., conducting tests every 500 ms).
Prevalence estimates of current(past 30-day) use of seven tobacco products were assessed; differences over time were analyzed using multivariable regression(2011-2018) or t-test(2017-2018).
The TOST test uses Student's test to check the equivalence between the means of two samples. A detailed description of such tests can be found in the chapter dedicated to t tests.
We study the mean of the calculated differences for the n observations. If d is the mean of the differences, s² the variance of the differences and D the supposed difference, the statistic of the t test is given by.

つの片側t検定は、「真の平均と仮説値の差は、閾値を超える」という帰無仮説の検定です。
Two one-sided t tests are constructed for the null hypotheses that the difference between the true mean and the hypothesized value exceeds the threshold.
