How to run a one-way ANOVA in SciPy (with Code)
Call scipy.stats.f_oneway with the independent groups as separate arguments and equal_var=True for the classical equal-variance ANOVA.
How to calculate a confidence interval for a sample mean in SciPy (with Code)
Pass the sample mean and its standard error to scipy.stats.t.interval, using one fewer degree of freedom than the sample size.
How to run a one-sample t-test in SciPy (with Code)
Call scipy.stats.ttest_1samp with popmean set to the fixed reference mean you want to test.
How to run a paired-sample t-test in SciPy (with Code)
Use scipy.stats.ttest_rel(after, before) when each after measurement is matched to the same subject in before.
How to run a Welch two-sample t-test in SciPy (with Code)
Call scipy.stats.ttest_ind with equal_var=False to compare the means of two independent samples without assuming equal population variances.
