WebFeb 22, 2024 · T-test in Python Statistics Let’s talk about T-tests. Such a test tells us whether a sample of numeric data strays or differs significantly from the population. It also talks about two samples- whether they’re different. In other words, it gives us the probability of difference between populations. The test involves a t-statistic.
