Through this article, we discussed what a two-sample t-test is and how to conduct it in Python. As we learned, there are three main methods to do the test: usingSciPy,pingouinandstatsmodels. Those three methods
单样本t检验用于检验两个总体的均值是否相等。两总体都是未知的，且我们不想或不易测量出总体所有的个体，来求得总体均值。所以我们从总体中随机抽样得到样本。对两样本进行统计检验，来看两样本差异是否显著。为使 two sample t-test 结果有效，需要满足一些条件。其中： - : 样本均数 - ...

t_test() [rstatix package]: the result is a data frame for easy plotting using the ggpubr package. t.test() [stats package]: R base function. Interpret and report the two-sample t-test Add p-values and significance levels to a plot Calculate and report the indepen...
1) Compute independent t-test - Method 1: The data are saved in two different numeric vectors. # Compute t-test res <- t.test(women_weight, men_weight, var.equal = TRUE) res Two Sample t-test data: women_weight and men_weight t = -2.7842, df = 16, p-value = 0.01327 alternativ...
The recovery time (in days) is measured for 10 patients taking a new drug and for 10 different patients taking a placebo. We wish to test the hypothesis that the mean recovery time for patients taking the drug is less than for those taking placebo. The..
