Python is a powerful language to be used for performing various statistical tests. One such statistical test is the Welch’s t-test. When there are two datasets with equal variances and you have to find out whether their means are the same or not, then using a two sample t-test would be wise enough. However, if the variances of the two datasets are not the same, then Welch’s t-test should be used to compare the means. Syntax stats.ttest_ind(dataset_one, dataset_two, equal_var = False/True) Here, ttest_ind is the function that performs Welch’s t-test. It takes three parameters, The first ... Read More
