Another way we can perform a two-sample t-test is by using thepingouinpackage. It is an open-source package based onNumPyandpandaswith statistical features. To usepingouin, we need to install it using thepipcom
two_sample_t_test_fl()函式是執行 Two-Sample T-Test的使用者定義函式 (UDF)。 注意 如果假設要比較的兩個數據集有不同的變異數,建議您使用原生welch_test()。 必要條件 資料庫必須啟用 Python 外掛程式。 這是函式中使用的內嵌 Python 的必要專案。
