One-Sample T-Tests

One-sample t-tests are used compare a sample mean to an expected population mean. They are used for a sample of one quantitative variable. For example, we could use a one-sample t-test to determine if the average amount of time customers spend browsing a shoe boutique is longer than 10 minutes.

Introduction
In this lesson, we’ll walk through the implementation of a one-sample t-test in Python. One-sample t-tests are used for comparing a sample average to a hypothetical population average. For exampl…

Implementing a One-Sample T-Test
In the last exercise, we inspected a sample of 50 purchase prices at BuyPie and saw that the average was 980 Rupees. Suppose that we want to run a one-sample t-test with the following null and alte…

Assumptions of a One Sample T-Test
When running any hypothesis test, it is important to know and verify the assumptions of the test. The assumptions of a one-sample t-test are as follows: - The sample was randomly selected from th…
