   Before conducting the two-sample t-test using Python let us discuss the assumptions of this parametric test. Basically, there are three assumptions that we can make regarding the data groups: 1. Whether the two samples data groups are independent. 2. Whether the data elements in respective groups follow any normal distribution. 3. Whether the given...

   Pingouin is a statistical-type package project that is based on Pandas and NumPy. Pingouin provides a wide range of features. The package is used to conduct the T-Test but also for computing the degree of freedoms, Bayes factor, etc. Firstly, let’s create the sample data. We are creating two arrays and now let’s perform two sample T-Test. For this ...

   How to run a two-tailed t-test in Python?

   • Let’s begin by running a two-tailed test, which only evaluates whether or not the two means are equal. It begins with the null hypothesis, which states that the two means are equal.

   How do I perform a two-tailed t-test?

   • The above works for a two-tailed t-test. If you wish to perform a one-tailed t-test, set the alternative argument to 'less' (the mean of the first sample is smaller than the mean of the second sample) or 'greater' (the mean of the first sample is larger than the mean of the second sample) as appropriate.
