Because the students are still getting used to functions in python, they tend to have many difficulties with this lesson. It does this by calculating the standard error in the difference between means, which can be interpreted to see how likely the difference is, if the two samples have the same mean (the null hypothesis). Web this means that anything that can be done to a traditional pandas data frame can be done to these results. Namely, the 2 groups do not affect/provide information to each other. This test assumes that the populations have identical variances by default.
T, p = ttest_ind(a, b, equal_var=false) This test assumes that the populations have identical variances by default. If you have the original data as arrays a and b, you can use scipy.stats.ttest_ind with the argument equal_var=false: Web this means that anything that can be done to a traditional pandas data frame can be done to these results.
