Скачать или смотреть Z-Test Explained

In this video, we talk about the z-test, a statistical method used to determine whether there is a significant difference between sample data and a population mean. We also discuss how it differs from the t-test, focusing on when to use each test based on sample size and whether the population standard deviation is known.
